One thing to note about staying in the heart of Madrid is how noisy it can get, which is a deal-breaker for me. I chose Mº Jesus's apartment because there was little mention (if any) of noise, and that proved to be true (thankfully!) It was very quiet all three nights (including Friday and Saturday). The location cannot be beat – we were visiting with a friend who arrived from out of town with an agenda oriented entirely around the center of Madrid and we were able to walk to everything very easily. I used to live in Madrid and was angling for another neighborhood a bit farther away but almost guaranteed to be quiet. It would not have suited our needs in the same way this apartment did. Very decent for 3 (or 4 people).
