We arrived at Martin's loft at 11 p.m., which was quite late, and Martin's girlfriend Helena was waiting there for us. She welcomed us to Madrid and to the loft and left us to enjoy our stay.
Communication with Martin was great, he explained to us everything about the loft before we arrived and was always reachable by Whatsapp.

The Loft's location was amazing - really central - and it was possible to go everywhere by foot, but it was also very quiet which was great. We had restaurants open until late at night and a supermarket open 24/7. The neighbourhood was quite ethnical.

I would definitely stay in Martin's loft again and would recomend it to anyone who wants to visit Madrid.
