Fabulous location within easy walking distance of all major sights. The flat was clean and bright and had everything we needed for our city break. Accessing the key on arrival was easy and security was good, with a key to the front door and the flat. The lift operates between floor 1 and 4, so some steps to climb from the ground floor to 1 and from 4 to the fifth floor. This operated with a key so also very secure. Nice cafe beneath - good for breakfast and pastries. A little noisy at night with the workmen washing the square but you can get used to this. Would definitely stay here again.
