The location is perfect for walking around the historic center and just a few steps from Chueca Square. There are a lot of bars and nightlife around, so if you are looking for a quiet street, this is not it! LOL
The apartment is spacious [for european standards] and super clean. Beds could be a bit more confortable, but it was not a big deal. We would recommend since it is a good value for the price and a great place to use as base to feel and see Madrid.
