The apartment is quite small but it had everything needed, a double bed, a small table and two chairs, small kitchenette and a bathroom. Kitchenette is a bit basic, but as the apartment is located in the city center, restaurants were easily reachable. Apartment was clean and it had an excellent Wifi and nice TV (which we didn't really use).
Water boiler was a bit small, the second person had to wait a while before having the shower.
Daniel was friendly and answered all questions promptly.
Ventilation is non-existent, but this seems to be the way everywhere in Slovakia. Window could be opened, of course.
