You can't beat this location in the heart of Madrid. It's a pretty lively area, so you can expect some noise, but that's what you have to keep in mind if you want to be in the heart of a city and close to everything. They have top of the line windows that do a pretty good job to keep the noise out, but you still will most likely hear some, especially on the weekends and at night. They have charming balconies, great amenities, and a good amount of space for four people. The sofa bed in the living room is much more comfortable than any pull out couch I've been on, and it's big. Most things are walking distance from here, as you are about 2 minutes away from sol. We had a problem with the wifi and someone came within 30 minutes to help us fix it - great communication!
