The apartment in Bilbao is very close to the Guggenheim Museum which was why we chose it. We were on a main street but the windows really kept the noise to a minimum. The apartment is nicely organized. Our only concern were some stains which Lucia said would be taken care of.
There was plenty of hot water, a nice dishwasher, great places to eat nearby, a couple small grocers, bakeries, and shops in the neighborhood. The bus stop to the airport is a block away from the front door.
If you plan to go to Bilbao, consider this place as a top choice. Our host responded quickly when we had a question about how to operate the induction stove. We had a great time in Bilbao and our apartment made it happen. Five stars!
