I went to Bilbao with 6 of my friends and we had a lovely stay in Asuncion's flat. The flat is clean and just as in the description. It is spacious enough to accommodate up to 10 people. The location is great - it is located in Casco Viejo next to many places where you can enjoy delicious pintxos and a glass of wine in the evening. It is also close to metro/tram station/taxi stop which allowed us to transfer easily to other parts of the city. (which can be easily reached by walk as well).
Asuncion is very responsive and helpful. We had some problems with electricity during our stay and she helped us straight away! We also arrived very late at night and this was not a problem for Asuncion.

Thank you Asuncion for being a good host! :)
