Rafael's place was very comfortable! My family and I stayed here for 4 days and it suited our needs well.
PROS: super clean, great location (within walking distance to major sites and lively neighborhoods with a lots of dining options, but also near the metro stops La Latina and Tirso de Molina), a nice amount of space for 4 people with 4 big suitcases, air conditioning (a must in July!), access to a kitchen and washing machine
CON: I specifically wanted to stay somewhere with an elevator but I learned while checking in that the elevator has been out of service for over a month (also, I'm a bit confused because it didn't look like there was an elevator at all in the building.)
