Mariano’s place is in the heart of it and close to the metro. He is a truly generous host and you have access to the whole apartment. The bedroom I stayed in is really only enough room for one person. Also, if you are sensitive to noise I would not recommend this spot. I slept fine with headphones but the building is not updated with new doors and windows so you hear most of what’s going on around you. Apartment is on third floor with no lift.
