We got another apartment not the one we booked. Oliver was very friendly and pleased to help at anytime.
The apartment was only superficially cleaned. Hair in the bathroom and under the furniture and beds a lot of dust and dirt. We cleaned our self.
The location is good (the park is nice and you can easily walk to all major sightseeing points in Prag) but sometimes noisy. There must be a Policestation or something like that nearby hence we heard in the night very often sirens. You can hear every step of the tenants in the apartment above
There is a supermarkt and there are many restaurants very close to the apartment.
If we would stay again at this place? Yes but we would take an other apartment not on street side and we would ensure that it is clean.
