We had bit mixed feelings about this apartment. The location is perfect and communication worked well but there were several small issues that all added up. The WiFI was very flaky during the first few days but eventually got fixed.
The listing description says that there is a dryer but when you book you will see the house rules that state that it is shared with three apartments and the cleaning service wants to use it between 11:00 and 15:00. Inside the apartment the instructions said that the silent hours are 08:00-18:00. We stayed for a week but every single time we tried to use the dryer it was full with somebody else's clothes and there was no basket where we could have moved their clothes. The outer door was often left unlocked so anybody in the building or inner yard could have stolen our clothes. This might not be a big deal but the listing does advertise "security first". Drying clothes inside the apartment was tricky as it was in the -1 floor. Keeping the windows open during the night caused insects to fly in. We believe the listing should clearly explain that the dryer is shared. We'd also recommend installing a simple mosquito net to at least one of the windows and equipping each apartment with a drying rack.
There was some dust and sand on the floor. The colleague who introduced us to the apartment wore outdoor shoes inside the apartment which explains this. We were under the impression that the Czech custom would be to not wear outdoor shoes inside. We'd recommend equipping the apartment with a vacuum cleaner.
The bed was bit worn out and easily made some weird noises. It seems parts of it were fixed with duct tape.
When we were checking out we noticed that if you open the door under the kitchen sink you can see that a small round plastic cap has fallen of the sewer pipes exposing the apartment to smells from the sewer.
