Let me start off by saying that Maria is by far the best host we have had in about 3 years of using Airbnb. She cares very much about providing her guests with a great experience, not just with her apartment, but in her city, Bilbao.
Maria went well 'above the call of duty' as a host. She provided us with all sorts of goodies in the fridge, a great selection of tourist guide material, helped us with finding restaurants and arranging taxis, and suggesting tourist activities.
Her apartment was beautifully decorated, well equipped, extremely comfortable, and centrally located. it was a short walk from the Guggenheim as well as many other attractions.
We were in her apartment for five days, and she helped us with one thing or another every day. And on our day of departure, she even got up at 7AM to call a cab for us to take us to the airport.
Maria has set a standard that other Airbnb hosts will find challenging to meet or beat.
