Thanks to Carlos and his collegues, we had had a wonderful stay in Madrid. The cleanness, facility and location, everything was perfectly explained in the information. And all functions very well! Carlos and his collegues were ready for us at our check-in, so we had no problem to enter the apartment even though we arrived a little bit earlier to the check-in time, and we could continue our travel smoothly. We appreciate that so much.
The street is basically quiet, but its neighbourhood is a bit noisy with restaurants. However the window of the room with sound insulation keeps the room quiet even in the weekend if you close it. So I didn't see any problem to sleep :) I recommend this facility!
