Melvin was a great host.
He picked us up at the metro station 'callao' and brought us to the apartment. It was no problem that our train was three hours late. He gave us some helpful tips about sightseeing in Madrid, left us a map.
He also left us some water, beer and wine as a welcome gift!
The apartment is small but enough for a couple of days. It is direct in the middle of Madrid, you don't need to take the metro, everything it's reachable by walking.
The apartment is in the back of a very big street with everything you need for shopping... It is not that much noisy as we expected!
All in all, we are sure that we would book the Apartment again! Thank you very much!
