The apartment is great for a weekend break. It's incredibly central. You'll be able to walk anywhere. Despite the central location, it is very quiet and I had a great sleep.
The stair is steep and it is unusual to have the toilet downstairs and the shower upstairs in the bedroom. But it wasn't a problem for us and added to the cool quirkiness of it.
The apartment looks just like the pictures and I thought it was very good value for money. I would certainly recommend it to friends.
Finally, Klara, the host, was very nice and flexible. Great communication throughout. A++ host!
