If we could give it 6 stars, we would. We stayed there in Dec'15 for 5 days. The location of the apartment is perfect. Within short walking distance from so many places - the Sunday flea market, a Metro station, Plaza Mayor, the king palace, 100's of good restaurants, etc.

The apartment itself was recently renovated and is very well equipped with everything you can think of (and there is a supermarket just 1 minute away in case you're missing something..) Wifi worked flawlessly (and we stayed there with two teenagers!), central heating was good, great showers, comfortable beds and beddings. The apartment is on a 1st floor with elevator. Street noise was not an issue.

Ernesto and Antonio were excellent hosts. Very responsive to emails before and during the stay. Provided us with useful information about airport transportation and local businesses. We had some issue with our departure flight and the hosts were very flexible and helpful with that.

In short - highly recommended! We loved Madrid and hope to be back one day. Will definitely come back to this same apartment if available..
