I stayed here alone and only needed to stay on the first floor. I had everything I needed there and really loved the location. I am not sure how it would be staying there with a group but I would definitely stay there again! If you are coming to Madrid for the first time, you can take the express bus to Atocha from the airport (5 Euros) and then it's about a 10-15 minute walk to this spot on one road (no twists and turns). Easy peasy. Thanks for a lovely time!
