BOOK! This place is great! It's super clean and just as described in the listing and in the pictures. The location is perfect. You're literally in the center of Madrid. We didn't have to take a cab/uber anyone because everything was walkable from the apartment. There are a ton of little shops right by and places to have a tapa or drink which is really convenient. I really appreciated the ability to wash/dry some clothes while I was there too and didn't need to worry about taking or buying detergent because there was some there. I needed a little help figuring out the train situation to another city and Vanessa was easily accessible to answer my questions. Again, I'd highly suggest booking this apartment. You don't be disappointed :)
