Highly recommend. Lots of light from big windows. Great location and quiet (a small amount of street noise), with a view of charming apartment buildings with wrought iron balconies across the street. There is a lovely plaza at one end of the block with great tapas bars along it, and there are restaurants, stores and bakeries just a few minutes in the other direction. Very comfortable queen size bed. We had trouble with the dishwasher 4 times in our 13 nights there; each time the host sent a repair person that day while we were out (two time a problem with the door and two times the circuit breaker flipped and we couldn’t fix it to restore power). We can say that the host was super responsive each time. I hope and assume that the problem was ultimately repaired, but we had to leave before we found out.
Our trip in Madrid got extended by a week, and we would have continued staying in this apartment for that week if it had been available. That’s how much we liked it.
