The flat is located in a very centric and convenient area of Bilbao. Near to all amenities, restaurants, plenty of supermarkets around and near to metro station and buses.
The flat is well decorated and well stocked. The bed is very comfortable, which for me is indispensable.
Obviously it is within a big residential building and it is not precisely quiet, but understandable for the centric location. Probably a bit dark.
Overall a good choice.
