The location is great! It's right next to the major train station and attractions in Madrid. It's really secure and I really liked that. There are 3 doors you have to go through before you get to the apartment door.
I gave 4 stars just because the previous guests (or whoever was in charge) did not remove the trash from bathroom and kitchen and so I had to do that for them. Also, for paper towels, the previous guests had pretty much finished them and there were only a couple left but Javier was gonna charge me 5 euros for more even though they were almost gone. BUT other than that, no complaints - it's a nice, stylish place, perfect for 2.
