Communication and service were excellent. Offered and provided a minibus for the airport pickup, one day (Sunday, of course, haha ) wifi was broken, a guy arrived within 1 hour and repaired it.
Location is pro, safe, relatively silent location. (Chinese restaurant in the building is great!)
Cleanliness had some problems, the floor was crying for some extra wash... houseshoes highly recommended!
Unfortunately, the bathroom was stinky, some disgusting smell came from the drain from time to time.
There were only 3 towel sets however the apartment is recommended for 5 or even 6 persons. (4 is comfortable, though.)
The main walls are thin, every word was heard from the neighbors. The kitchen is well equipped (however recommend replacing the old frying pan...).
