Felipe was an amazing host, very friendly and accomodating. Before I went to Madrid (I came from Barcelona) he told me what the cheaper ways of travel were, which was a great help!
The accomodation itself was okay, especially in a price/quality ratio. The city centre is within walking distance (about 15-20 minutes), and there are plenty of breakfast and coffee places around to enjoy throughout the day.
The appartment was clean and had about everything you could need. Felipe even let me use his spices to prepare food. The room itself was for my two-week stay maybe less favourable. The single-pane windows let through a bit too much light and noise at night (every night there are garbage trucks driving up the streets until 3:30am). The mattress could also use an upgrade.
Overall I would recommend this place for a shorter stay, since I wás satisfied with my experience in the end.
