Miguel was a great host - he was super understanding when we arrived later than expected and he was very communicative whenever I had any questions.
The apartment is very cute, modern and clean. It accommodated me and my friend perfectly. Miguel provided us with all the commodities needed for our comfort (towels, shampoo, etc.). The apartment was quite quiet, considering how incredibly central it is. We were at a walking distance to pretty much all the places we wanted to visit, and there's also two metro stations very close to the apartment, so we never felt too far away from anywhere. I also loved the wi-fi connection, which was the fastest I've ever experienced outside my own home!
I'll definitely stay here if I ever visit Madrid again!
