Adriran and Miguel's apartment was wonderful, even better than we hoped. The living/dining room, primary bedroom, and primary bath are large. The kitchen, second bedroom, and second bath are smaller, but quite lovely.
The location is very central. In fact, we were unsure if the apartment would be noisy, given how close it is to Plaza Mayor. In fact, noise was rarely a problem. (We visited in January.) During the day, the apartment is almost entirely quiet. At night, there are occasional bursts of noice (the shops closing their gates, the trash being picked up), but overall there was no ongoing noise. These disturbances are an issue only in the main bedroom; the smaller interior bedroom is almost entirely silent.
From checkin to checkout, we had a wonderful visit. We'll certainly stay here again, if we can.
