We had a very pleasant 7 day stay!
The location is absolutely perfect, right in the center of prague with only short ways on foot to get anywhere we want.
Despite this it was very quiet in the night which we definetly appreciated.
The apartment is beautiful and had everything we needed (Dishwasher, Washing machine, dryer, microwave, etc.)
The system to turn on lights/close curtains took some figuring out and occasionally worked only after a few tries but it didnt bother us much.
One thing i noticed is that the apartment gets dusty quickly (it was clean when we arrived but got fairly dusty after 3-4 days) so people with allergies should take that into account.
Other than that the communication was perfect, i was responded to immediatly and our host actually brought us new towels and bedsheets ahead of time.
All in all, despite a somewhat steep price, i would definetly recommend this apartment!
