Beautiful apartment right in the city center, three minutes away from Bilbao and Quevedo, in a very nice neighborhood, both for sightseeing and nightlife.
I did not meet Sylvia, but she was always attentive and replied very fast. I met Palany briefly, and he was very friendly and considerate.
The apartment was completely furbished, and the kitchen has all the appliances. One of the beds was a sofa (where I slept), but it was confortable.
The apartment is in the basement of the building. This can be nice in the summer, because it will protect from the heat, it makes the apartment kinda dark, but I guess most people will be outside most of the day.
