Perfectly located appartment! It was located very close to the city centre and next to the entrance there is a subway station. The sofa bed was very big and comfartable as well, so you can easily stay here with 4 people. You need to pick up the keys on another location than the appartment, which is all the way on the other side of the city. So keep in mind that it might take a little longer to arrive at the appartment.
All in all we enjoyed our stay a lot, the city is amazing!
