The apartment was great, had all the listed amenities and more. It was super comfy and clean. The beds were soft, the air conditioning worked, the shower had great temperature and pressure.
The location was very good, many restaurants, pubs and coffee shops nearby. Despite being a busy neighborhood, the apartment is located at a quiet street. Within a 10 minute walk there is a subway station (subte Linea D), which was quite helpful.
Gabriela also lent us a SUBE card so we could use the subway and buses of the city. That was a very welcomed surprise. In addition to that there was also coffee, tea, toast and jelly at the kitchen when we arrived.
The self check-in went smoothly, it was very easy to enter and leave the apartment. We also had a problem with our flight, which was delayed and Gabriela kindly let us check out later than the original time.
Overall we had a wonderful stay. I would highly recommend it :D
