We spent 3 nights at the Cloisters Inn. From the minute we arrived at midday the staff were very helpful, although the rooms were not ready until 2, we were able to leave our bags in a secure locked room until 2. We were given a map of Prague and the wifi password, and pointed in the direction of free tea and coffee. The room it's self was big enough and air con was great as it was very hot when we visited.
The fridge had free water and beer on our arrival.
The breakfast ranged from cheese, cold meats, eggs, sausage and beans with different breads .
Throughout the stay the staff were very helpful and very polite.
I would highly recommend the hotel.
