I loved my time at Columba's place! She's an incredibly kind and welcoming person, and clearly loves her city and sharing amazing personalized recommendations for your trip. The apartment is beautiful, with a lovely balcony with a great view, tons of plants, and everything is super clean. The room is quiet and the bed is really comfortable. The wifi is strong enough for remote working / video calls. The area is great, close to the bus / train station/ beaches / old town, but in more of a local neighborhood. Couldn't say anything negative about this place, I'll definitely stay again next time I'm in San Sebastian!
