We loved this apartment. It felt spacious (for three of us) and was very clean. Rafael's helper met us right on time and was very helpful in showing us the space and giving us restaurant recommendations. We walked to all of the major sights with no problem.
There is some minor street noise in the front bedroom, but it's to be expected in the middle of a city and it wasnt anything a pair of ear plugs couldn't fix. I will definitely book this place again on my next trip to Madrid!
