The apartment is located right in the middle of the historic center and thus close to all attractions and Plaza Merced, Calle Larious, etc. It was quite easy to check in using the Libere app.
However, I wasn't aware that place was more like an unmanned hotel than one concrete apartment. Thus it was a bit disappointing to find out that the apartment I rented was on the 1st. floor and didn't correspond to the pictures posted on Airbnb, which seem to be from the roof apartment. The 1st. floor apartment was substantially more dark, seemed a bit smaller and was also exposed to noise from the street though it wasn't that bad in January, when I stayed there. However, in the summertime I imagine it could be more of a problem.
The level of cleaning was high, but the soap dispenser had fallen of the wall and the bathroom had a vague smell of sewer.
The rates seemed attractive, but I would definitely ask for another floor before booking next time.
