This flat was great for an extended stay (3 weeks). It was very clean, with modern fixtures and features and good light. The main seating area/kitchen is rather compact (which met expectations, as it was clear from the description and photos) but more than fine for me as I was a solo traveller. I had basically what I needed in the kitchen to cook my own meals for several days. There wasn't much noise, although I was there in the winter so the windows were closed most of the time. To give clarity about stairs (as seen in other reviews): there are two flights of about 12 steps each straight up to the door of the flat, then another flight inside the door of another 10 steps to reach the inside of the flat itself. I did not find this to be a problem at all but thought it might help others when considering whether to book. Sergio was quick to respond to questions and the whole process was smooth. The location is great: easy access to metro, very walkable, groceries and restaurants nearby.
