Irina's apartment is rather small but very well organized and located in a great area of Madrid (nearby the lovely Sabatini garden and royal palace). There are plenty of food shops nearby (Carrefour Express, a very nice bakery etc..) and it is just 5 minutes walking distance to the rail station Principe Pio. From the airport you can either the metro (you have to change once) or the Cercanías (it's a direct trip!). The communication with Iryna was quick and easy. We really enjoyed our stay in Iryna's apartment which we can recommend.
