This flat has a perfect location in the old town. It has a great price to value ratio. All in all, it's a really good accommodation, but I have to note some misinformation.
There is no elevator in the building, just a service elevator (and it was out of service too).
The washing machine and the drying machine are located in a separate community laundry room. The drying machine was used during our 6 days stay so It's almost impossible to use it.
The flat was cold during our stay because it has central heating which is regulated automatically.
We were 4 of us, but the accommodation is available for 5 persons too, but note, that the fifth person should sleep on the couch which is not a folding bed just a simple sofa.
One more thing. From our side, it was totally fine and we expected it, but the flat is located in the party district so it's not the most silent part of the city.
