My stays at Daniel's are always very good. All of his rooms are excellent! They are very clean and very well maintained. Laura is the on-site host, and she is very helpful and accommodating.
There is a lift to the apartment which is centrally located and close to busses and metro. The Guggenheim Museum is a 15 minute walk along the river.
I stay at Daniel's whenever I'm in Bilbao. It's so clean and convenient!
