Our group of five stay here three days in August 2018. The review will be a bit boring - for us, this property was excellent in these respects:
Location- the apartment directly overlooks the ancient cemetery in Old Town. There are many restaurants within two blocks, a couple of opera houses even closer, the Charles bridge perhaps six blocks. We're in out 70s and 80s and walked to most attractions.
Cleanliness - Perfect. We saw no problems.
Facilities and equipment - The apartment has 1 1/2 baths in excellent condition, the kitchen is well equipped.
Response and communication - Again, perfect. The introduction to the apartment was thorough, and the airport shuttle Hana secured for us (at 4:30 AM!) was there five minutes early.
In summary, this unit is in excellent condition and is professionally managed. I recommend it without qualification.
