Paula's flat is in a fantastic location about 10 mins walk from Atocha train station, other public transport and 10 mins walk to all the major museums and Madrid's botanical garden. The flat is comfortable, nicely decorated and has all the main amenities you'd need. There were three of us and our teen daughter slept on the pull out sofa so we're were all in one space. Could feel too tight for some but for two nights it was fine us.
The flat is close to great restaurants and nightlife yet quiet enough for sleeping. We had a great time here and highly recommend this host. Paula was helpful in giving suggestions for some of our activities and responsive if we had questions.
