The apartment is in a close to perfect location to explore the center of Madrid, with lots of restaurants and cafes close by and a Metro Station around the corner. The apartment itself is neat, clean and has all the necessities.
Unfortunately the neighbors are extremely noisy and it carries all the way to the bedroom / only room in the studio apartment. During my last night someone was in the courtyard / outside coughing continuously in the middle of the night (2 am). You wake up to extremely loud conversations and repetitive phone calls on speaker phone, which sound as if they were conducted in your bedroom. I would be only able to sleep under those conditions with heavy duty construction ear protection. You also only have privacy if you keep all blinds down, so it is rather dark.
Ana is a very nice host with good and responsive communication. I really hope there is some way to address the noisy neighbors, which make a stay at this otherwise lovely place pretty unbearable.
