Perfect location: few meters from Old Square but in a private yard, very quiet. We spent 2 nights in January and the room was very well heated. (very important in Prague in these days) All you need in the room- kettle, toaster, pots and dishes, cutlery, fridge, you name it. Even tea , sugar and coffee supplied. Very nice people, willingly to help with info about transportation, restaurants, events. Next door you can buy tickets for concerts , tours, events. Downstairs they run a coffee shop which is a very nice stop over on the way out or in 🙂 Bed was big and comfy, good quality and very clean sheets and towels. Room is quite big - queen size bed + sofa + table + kitchen and plenty of space to walk around.
I highly suggest for anybody that wants to visit Prague any time of the year ;))
