I will start with the positive things - apartment is large and clean, located quite centrally and close to a metro station.
Now what we didn't like.
- you can't tell it from the photos but one of the double bedrooms has no windows! there is no air conditioner either in that room, we stayed in September and even then it was hot and no fresh air in that room. can't imagine how bad it is in summer. Mattress extremely hard and not comfortable too.
- Small bathroom has a terrible sewage smell, which makes it completely unusable. We were a family of 5 and I was specifically looking for an apartment with 2 bathrooms but in the end no one wanted to use the small bathroom because of the smell. Host should either fix the issue or list it as a 1 bathroom apartment.
- apartment is very very noisy, construction works around
- check in process not convinient. instead of organising a self check-in the host wants you to give them exact time of arrival and charges extra 20€ for check-in after 10pm.
- slow and not reliable internet connection.
overall, not recommended unless the host can fix the listed issues.
