Eloisa was super nice, allowed me to check-in earlier and check-out later, and she speaks English, which as it turned out is a rarity in this city. The person who gave me the keys - José was also incredibly nice and gave me so many cool recommendations for places! The apartment was very nice, though much smaller than it appears in the pictures, but that's understandable. It was cleaned very well, the bathroom was super clean, etc.
My only issue was that the kitchen utensils seemed worn out and not super clean. I was planning on making dinner in the apartment, which is why I decided to pay more for an AirBnb with a kitchen, but I ended up eating out all the time because I was a bit grossed out to cook there.
The hot water came from a small boiler so if you have long hair you will have to hurry up a lot because it may not be enough.
There is no power outlet near the bed (only one, but already used for a reading light) and it was a bit inconvenient but not a big deal.
Overall I had a nice stay but you should keep in mind that it might be too small for a couple.
