Maria Anna’s place is very comfortable! The space was clean and the bed very cozy. The common areas are clean and organized as well. Maria Anna was very welcoming and very helpful despite the language barrier. The only thing I would note is the set of rules in the room, including no usage of the stove/oven, time limit in the bathroom, no trash disposal in the room, etc. It seemed rather strict and these might be helpful to know before booking, especially if you plan to stay for several days and would like to prepare a meal. The rules also state that bag storage after checkout is an additional 10 euros, but we were asked for 15. Overall, a comfortable and nice stay for one night near the central Madrid attractions.
