We stayed in the luxury old convent with 5 friends and had a great time. The location in the middle of THE tapas street of Madrid was terrific. As the walls are very thick you don't hear the noise outside. Being close to the market with fabulous food and the Plaza Mayor is a real advantage.
The apartment is very spacious with a large hall and a large living room and kitchen with all equipment (but who wants to cook with so many tapas around). There are 3 bedrooms with bathrooms and a also separate toilet. Around the corner is a super bakery with fresh break and all sweats you can think of for breakfast. Don't forget to bring cups for the nespresso. Towels and sheets are available. Gabriel even brought milk, juice, bread and fruit etc so we did not have to look for a grocery store. As the location is perfect we did everything walking. Please keep in mind that you have to climb 3 interesting stairs and there is no elevator, so it is not wheelchair accessible. it was the best choise we made, so much more fun than a hotel.
