Our stay here was fantastic! The apartment is just as beautiful as all it looks from all of the pictures, and very comfortably fit our group of 7 (with room to spare). It's also very centrally located. We were able to hit all of the tourist sites we had on our list (the royal palace, Retiro park, the Prado, as well as all the best restaurants, bars, and clubs) without ever needing to use a car, bus, or metro.

I would definitely recommend this apartment to any group wishing to have a great time in Madrid.
