We stayed at one of the apartments in the building for 4 nights.
This was not a typical AirBnB experience as this was a building of a few stores with multiple apartments for rent. Apparently this was just a renting business but neither a well managed guest house nor a private apartment rented by owner.
The check-in instruction was sent in advance, however the key box had a wrong code, so we could not pick up the keys ourselves. The office was closed (although it was about 15 mins till working shift end), but fortunately there was a housemaid who helped us.
The apartment was kind of sole-less, stuffed with Ikea only, like bare minimum. Kitchenware was quite poorly cleaned: sticky spots on dishes, juice traces in the fridge (which apparently was not de-frosted for a few months). An iron with burnt surface. All these were various signs of limited care/management. However a bed was good to sleep, A/C was well functioning, and the room was reasonably clean.
Communication with Carlos was generally fast but sometimes with duplicated requests (which is probably due to being overwhelmed with managing this renting business).
Check-out was a bit weird - the housemaid and others just entered the room without prior checking, and one of us was just exiting the shower :-\.
Overall we had mixed feelings - OK to stay for a couple of nights but unlikely to stay again. Current value for money was OK but lower than what the same money could give you 2-3 years ago.
