The apartment 2C is very spacious and comfortable for the five of us.It's on the 5th floor of a building with offices and apartments, with an elevator. I t has 3 bedrooms - 1st with a double bed, 2nd with a double bed and two single beds and 3rd with a double bed and a baby cot. The beds are comfortable and great to sleep in. It has 2 bathrooms (one with a shower and one with a tub), a fully equipped kitchen (with everything you could need) and a living area with a big tv. It has air conditioning i think in every room, but we didn't need it so i assume it works just fine, like everything else in the apartment (the dishwasher, the dryer, the wi-fi, the water-cattle, the microwave, hot water was always available etc.).
The location is great, right next to Narodni museum - 15min. light walk to the main square (with the astronomical clock) and 2 metro stations only 5min away. It's in the center but in a quiet street, so you can have a good sleep and rest.
Romana as a host is very professional and easy to communicate (either before the arrival and also during the stay). On request she organized the transportation from and to the airport (for us 5 it was 32euro) met us at 10:00h, since our flight was really early, then let us leave our luggage till check in and after check out, at the reception in the building.
None of my friends, and I, have any remarks for this property and Romana as a host, and we warmly recommend it for everyone that wants to enjoy Prague to the fullest.
