We stayed at this apartment for five days because of its very good reviews. However we were quite disappointed. In our experience this apartment is not suitable for such a long stay, especially in summer. Even though the description of the apartment specifies there is no AC it was simply not livable and we couldn’t sleep. In addition, we found the bed to be too small for two (140 cm) especially in the heat. You can’t open the windows either to get air since you are eaten alive by the mosquitos at night.
Regarding cleanliness, it really depends on your standards. We consider that lumps of dust under the furniture, on the lamps and the night table is not acceptable, especially for the price we paid per night. Also the bed sheets had stains when we arrived which made us feel very uncomfortable. Luckily we found a new set in the draws of the apartment which enabled us to change them.
Finally, do expect to hear each and every step of the neighbors upstairs and their discussions as the soundproofing of the building is poor.
This being said it is true that the building is very close to the center.
