Alfonso´s apartment in Madrid was exacttly right for us. We were there on our last few nights in Spain and we really enjoyed it. The apartment was well-equipped. The bed is small though so we made use of the fold-out couch in the living room. Also, the building has an elevator which was a great feature for us, as we had a couple of heavy suitcases.
The multi-cultural location was great; we walked to all the spots we wanted to visit. We would recommend this apartment and would return if we were to visit Madrid again.
