I really enjoyed my stay at this apartment and would stay there again. The location is perfect: it's in the middle of all the fun of Barrio las Letras but on a quiet street, just steps away from the subway and within a 15-minute walk from major landmarks (Prado Museum, Retiro Park etc). Tons of restaurants, bars, grocery stores etc nearby. The building is old but full of charm. The apartment is very cute, super clean and comfortable. Nice bed. Lots of natural light even though it's in the back of the building. I don't think this apartment works for people with accessibility issues. There is no elevator, so you have to climb lots of stairs. The bath tube can feel a bit dangerous/slippery. Also: no starter condiments in the kitchen, and you can hear your neighbors (though they were not too loud). Again, with that said, if you're in great health and want a comfortable/authentic place in an excellent location, this is it!
