We enjoyed the stay in Xabiers Appartment very much. The communication was fast and flexible (we had quite some problems with short term flight cancellations and delay of our arrival time). Ines, a friend of Xabier, was waiting in front of the appartment and gave us a tour of the appartment. It is conveniently located in the old part of the town, with lots of restaurants and tapas bars to choose from. Public transport is near by, the airport can be reached by tram/metro and airportbus in approx 40 minutes.
The rooms were clean, the beds very comfortable and the appartment offered everything we needed. Both bedrooms are spacy and offer lots of wardrobe space. The two bathrooms (each with sink/shower/toilet) are on the small side but sufficient enough.
On the weekend nights, the noise from the street (people partying) could be heard in the the bedroom (towards the street) so if you are a light sleeper either bring some earplugs or use the other one on the back of the appartment.
We can recommend Xabier´s appartment to everyone who wants to stay right in the heart of the casco viejo.
