If you want to stay in a quiet zone, far from the centre, this is the place. The hotel is clean, the beds are comfortable and you are welcomed with a bottle of water and coffee maker in the room (with capsules) There is also a tiny fridge.
The things I didn't like too much, is that there is no air conditioning in the room!!. When I arrived, it was like they'd put a heater in front of me, even though the window was open (It was a very bright, sunny day in Prague this day, and very hot too!). I asked the receptionist to do something, but no one cared about it. A shame. Other than that, the fridge in the room was a little bit audible at night (if you are like me exhausted, you hardly hear it while sleeping).
To sum up: quiet and safe zone far from the centre, quiet hotel at night, good service, but the room a little bit too hot without air condioning for my liking. I recommend this place.
