Enjoyed our stay on the whole, didn't end up using the trams, Uber into central about 5-10 Euros.
The living room is the best part of the apartment.
The beds/matresses are also very good and the linen etc very clean and fresh.
The only downside to our stay were the towels - they were hand towels not bath towels, luckily for me I have no hair but it was very inconvenient for the girls.
The light in the toilet also did not work for the first night so had to use the light on our phones when we went to the toilet. Marcel fixed this for us on the Saturday though
