The apartment is very nice, big and bright. We absolutely loved the location, close to everything We needed and wanted to see. The host very polite and helpful. He Was waiting for us on arrival and was easy to reach via WhatsApp.
The only con might be the water heater. We were the party of two and when one wanted to take a shower after the other, there werent enough hot water in a tank.
Beside that - I strongly recommend this place for anyone visiting Madrid!
