Sofia is a pleasant, walkable city of 1.2 million people. Neighborhoods matter: the city centre (Vitosha Boulevard, Alexander Nevsky Cathedral area) is touristy, modern, safe, and lively. The Zona B medical district (where many clinics cluster) is quieter, professional, and clean. Both are accessible; walking between them takes 20–30 minutes.
Getting around: Public transport (metro, tram, bus) is efficient and cheap. A 10-ride ticket costs BGN 10 (€5). Download the "Sofia Transport" app for real-time routes. Taxis are everywhere; use Uber or Bolt (app-based, fixed prices) instead of street hailing to avoid overcharging. Walking is very safe in city-centre areas during daylight and evening. Avoid isolated areas after midnight.
Weather and clothing: Sofia has four distinct seasons. April–May and September–October are mild (15–22°C), ideal for walking. Summer (June–August) is warm (25–30°C); bring sun cream and water. Winter (December–February) is cold (0–5°C); bring a coat. Spring and autumn require a light jacket. Comfortable walking shoes are essential—many streets are cobbled.
Money and prices: Bulgaria uses Bulgarian Lev (BGN), pegged to EUR at ~1.96:1. ATMs are everywhere; withdraw cash or use cards—most shops accept both. A coffee costs BGN 2–3 (€1–1.50). A good lunch costs BGN 12–20 (€6–10). A beer costs BGN 2–4 (€1–2). Sofia is cheaper than Western Europe.
Restaurants and food: Balkanic cuisine is hearty—try banitsa (cheese pastry), moussaka, shopska salad (feta, tomato, cucumber), and kebab. English menus are common in tourist areas. Google Translate helps in non-touristy spots. Avoid street food unless it's from established vendors. Markets (Women's Bazaar, local produce markets) offer cheap, fresh food if you're staying in an apartment.
WiFi and phones: Most cafes, hotels, and restaurants have free WiFi (ask for password). If you need local data, buy a SIM card at the airport (€15–30 with generous data, typically 20 GB) or use your UK roaming (usually €1–2/MB with most providers; watch usage). Mobile numbers in Bulgaria start with +359; clinics and services will use this format.
Where to rest during treatment downtime: Your accommodation (apartment or hotel) is your base. If you're resting between sessions, a quiet apartment with a bed and internet is ideal. Coffee shops are good for sitting with a book or laptop. Museums are air-conditioned and walkable (National Gallery, Bulgarian History Museum). Parks (City Garden, Yuzhen Park) are pleasant for slow walks.
Things to see (if energy permits): Alexander Nevsky Cathedral (impressive Orthodox cathedral, free entry, quiet inside), Vitosha Boulevard (main pedestrian shopping street, people-watching, good for slow strolls), Boyana Church (medieval frescoes, 20 mins outside city, worth a day trip if you're well), Woman's Bazaar (atmospheric market, cheap food and souvenirs), Street art in Oborishte district (colourful murals, Instagram-worthy).
Bathing and swimming: There are no beaches in Sofia (mountains surround the city). Swimming pools exist but are mainly for locals. Thermal spas (mentioned elsewhere) are available if your clinic recommends. Otherwise, relax in your accommodation.
Safety: Sofia is very safe. Petty crime exists (pickpockets on crowded transport, occasional theft), but violent crime against tourists is extremely rare. Use common sense: keep valuables out of sight, avoid walking alone in dark isolated areas late at night, use official taxis or apps rather than street hails. Police are professional; if you need assistance, dial 112 (emergency) or 166 (police non-emergency).
Language: English is widely spoken by people under 50, especially in city centre and medical areas. Older residents might not speak English. Learn a few words: "Blagodarya" (thank you), "Mozhete li na angliyski?" (Do you speak English?), "Smetka" (bill/check). Google Translate is your friend.
Cultural norms: Bulgarians are polite, quiet, and direct. Eye contact is normal and respectful. Handshakes are common when meeting. Tipping is not required but 5–10% is appreciated for good service in restaurants. Dress modestly in religious sites; cover shoulders and knees.
Pharmacies and medications: Pharmacies ("Apteka") are common; look for the green cross. English-speaking pharmacists are available in city-centre branches. Over-the-counter painkillers, antihistamines, and cold remedies are cheap (BGN 2–5). Prescription medications are available if you bring a letter from your clinic or GP, though some antibiotics are controlled.
Internet and communication: WiFi is reliable. Calling/messaging your clinic or family: WhatsApp, Viber, or Skype are free on WiFi. If you need a local phone number to give your clinic, buy the SIM card mentioned above.
Other healthcare if needed: If you're unwell (unrelated to treatment), there are pharmacies and walk-in clinics. For emergencies, dial 112. Costs are low (€20–50 for a doctor visit). Inform the doctor of your recent stem cell treatment.
Practical tips: (1) Keep your clinic's address and phone number written down and in your phone. (2) Take a photo of your accommodation address (useful for taxis if language is a barrier). (3) Download offline maps of Sofia (Google Maps or Maps.me) in case you lose connectivity. (4) If you feel unwell during a treatment session, your clinic will manage it; don't panic. (5) Rest is your priority; over-exertion during sightseeing defeats the point of treatment.
Bottom line: Sofia is walkable, affordable, safe, and welcoming. You can explore leisurely if you're well, or rest quietly if recovery is your focus. Either way, the city supports a comfortable week.
