My friends and I have just returned from Bilbao where we had an amazing stay in Xabier's apartment. His communication was excellent before we arrived and we were met by his lovely parents on arrival who gave us lots of information about what to see and do.
The apartment is just as good as the photos suggest and is beautifully decorated and immaculately clean. The beds are very comfortable, the showers are great and the kitchen has everything you need.
The apartment is in a good location for the Old Town and the Guggenheim. There are lots of good restaurants and bars within walking distance and some lovely cafe/ bakeries nearby for breakfast. The nearby garage was a bonus and we travelled about quite a bit which we would recommend. The countryside around Bilbao is beautiful and we would recommend trips to San Sebastián and Guernica.
We loved the apartment and Bilbao and would recommend both to anyone looking for a short break in an interesting city that is not overwhelmed by tourists (the locals are also very friendly and helpful).
