My wife and I stayed at this flat for a week after our travel plans changed last minute. The booking process was quick and easy, and the apartment was exactly as described in the listing.
We worked remotely throughout the weekdays and the wifi was great, enough for both of us to take video calls simultaneously without any interruption. There’s a supermarket directly below, and a bunch of good restaurants nearby, as well as walking distance to the Prado, etc. We thoroughly enjoyed our time!
