This place is in a building that I believe is composed of mostly other rental apartments. The location is fantastic, central but in a very quiet area at night. The apartment is spacious, the bed comfortable, the shower and water pressure excellent, and the internet works well. Natalia was friendly, although I got in very late so there wasn't much in the way of guidance through the city. But the communication was great, and she was waiting for me on the street when I arrived.
Please note that they will charge you a fee if you arrive late.
