We had a lovely time during our 4 night stay at Sofia's place in Madrid! The flat was well equipped with everything we needed and very clean. The location is perfect for exploring the city -- in a trendy, interesting, very central neighbourhood and walkable to everything that we wanted to do and see, along with with countless shops, restaurants, bars, etc. We took both the express bus recommended in Sofia's welcome letter and the train to get to and from the airport -- both were direct, inexpensive, and very easy to work out. Overall, we wouldn't hesitate to stay again or recommend to friends/family as staying at Sofia's made for a very easy and enjoyable trip.
