Pros: The apartment was clean and spacious. We were 8 people and there were enoguh space for all of us. The location of the apartment is quite central and the public transportation can be reached within 5 to 10 min. The neighbourhood was nice with lots of bars and restaurants. Petr was always answered my questions in the booking phase fastly.
Cons: The noise level and the air temprature inside the apartment is too high. We were there in the end of July and the apartment was too hot. At night, it was even hotter than outside. And if we wanted to open the windows to let the air in, the street in the front was too noisy with many cars passing by with relatively high speeds. So, we were not able to sleep well.
The door hinges inside the partment were too dry and they were also making a lot of noise. So, we had to lubricate them with oil. There was only one mirror in the bathroom which for eight people is not eough.
Petr sent a clloeuge of him for the check-in which did go smoothly. The woman who was in-charge of our check-in was impolite, aslo she came 15 min late and when she came, she was not able to open the door for us (because of some problem with the digital lock which could not be opened with the password). It took 15 min for her to open the door with the help from the neighbours. Since the front door password was not working, we got one key for entering the building and we were promised to get another exra key but after 2 days she wrote backe and said she could not.
To sum up, if you are traveling in summer, it is not recommended to stay here, otherwise in colder times I think it is fine.
