"The room was very clean and modern, WiFi worked great, air conditioning/heat was perfect, it has a very nice shower (with shampoo and body wash), and the unit had many amenities like a nice kitchenette stocked with all the necessities (such as a Nespresso machine and capsules, and a hair dryer). The room layout was a little cramped and oddly shaped, but it was comfortable. It was pretty quiet aside from some street noise and some other guests I could hear from time to time, and when the cleaning staff was doing the other rooms they were a little loud. They even came into my room on accident but were very nice about it. The building felt safe (although there wasn't a safe/lockbox in the room that I found). You need a code to get in the building and a key to go up the elevator. The neighborhood felt a little iffy for me when I arrived alone at night, but I didn't have any negative experiences. There are some restaurants and convenience stores nearby. Check in was slightly inconvenient- you have to type in one number to get in the building and then another to check in at a machine to get a key. I loved the rooftop during the day and at night - lots of chairs and tables up there (views aren't anything special but there's nice decor). Not sure I'd stay again but it is very convenient if you're going to a concert and it was only 20-30 by taxi to the airport (or about an hour by bus/metro). The metro into central Madrid took about 40 minutes and felt safe and generally convenient."
