The apt is wonderful, the location is fantastic, and the photos are accurate. It is a 2 min walk away from the Basilica de San Miguel, 5 min away from the Mercado de San Miguel & Plaza Mayor. The apt is spacious, quiet for sleeping, and has plenty of hot water for showers. Check-out was easy.
The only negatives were our check-in. Our taxi tried 2x, but could not figure out how to get to the very short street the apt is on. We tried calling many times both the host and her nephew who was supposed to check us in, sent texts as directed, and sent Airbnb messages from the airport before we left and from the cab. We did not get a response until after the cab dropped us off and we had to lug our bags several blocks and find the street and apt.
Tell your taxi to use Calle del Sacramento so you don't go through the frustration that we did. In addition, her nephew was supposed to check us in but he was not there (and was late in responding to texts/never answered his phone) so the cleaner let us in. Therefore we did not get a proper check-in with information on the area, maps, directions on the apt and how to use things, etc. There was a binder on the side shelves that was helpful, but we didn't notice it until right before we left.
Despite the horrible check-in, we would stay here again. It really is a beautiful spacious apt in a fantastic quiet location.
