We came for work purposes to Madrid as a family of 4 with 2 small kids. We stayed at Ignacio’s place for 2 weeks.
The location is amazing, close to everything but yet very calm.
The only thing that we were a bit disappointed about is that the whole apartment is ‘inside’ the patio and being a 3rd floor, its not that bright and all windows have close vis a vis. But I guess when you come for a short stay you don’t stay inside that much.
Otherwise, there is everything you need in this apartment and the people who manage it are very responsive and helpful.
