Everything was great during my 3-month stay: quick communication, easy check-in + check-out, very clean and modern flat, no major issues overall. The hosts were very kind, professional, and quick to help. The location is right next to the train station "Principe Pio" which was very convenient for the metro, medium-distance trains, and a train connection to the airport. Grocery store is around the corner, as is a shopping mall. You are right in the center, next to the beautiful "Casa de Campo" public park, the "Royal Palace", and "Plaza de Espana". The flat is small but functional and can sleep up to 4 people (1 bed in the bedroom for 2 people, 1 pull out couch in the living room that fits 2 people). But this is for 1-2 people, ultimately it's a studio apartment with a kitchen that separates the bedroom area and the living room area. Overall the flat is quiet as it is on the back side of the building, while the main entrance to the building is on a busy street. A few small things came up, such as construction in the building on the top floor which sometimes started in the morning, but that was out of everyone's control. Electricity went out twice during my 3 months there due to several things in the kitchen being used at the same time (oven, stove, fan/light above the stove, apartment lights), but it just required a simple manual reset of the electrical safety switch which brought back electricity right away. All in all, I had a very nice stay and can recommend the place. Thanks for having me!
