It was an amazing experience. It felt like staying at your kind and caring friends' house who provided you with all you needed and left small treats like milk for coffee and toast for breakfast. The kitchen was really well-equipped - if you don't feel like eating out you can cook a proper meal, not only sandwiches.
The design of the apartment is absolutely amazing - each item was chosen with great care, and it really suits. There's a lovely terrace, as well.
The location is really convenient - it's in a walking distance from the castle and the Old city. It will take you about 15 minutes to get to the Central Station. However, the area around is not overcrowded and noisy.
