This is my second stay at Javi's place.
What's good: The location is the best in Madrid, right in the centre and close to everywhere. The bedroom is small, but a lovely space that has lots of nice little touches. The host is friendly and helpful too, and in terms of amenities, like hot water, kitchen utensils, etc, the apartment has it all covered.
What could be improved: The living room (which is the nicest space in the apartment) was not fully included as part of the shared space this time around, which I was disappointed about. There was walking around in the apartment until about 3am each night which slightly disturbed me and at times made it hard to relax.
