We had a very nice time at Spencer Dock. The apartment was clean and very well equipped and I would definitely stay there again.
The hosts provided clear instructions on how to connect to the wifi, operate the heating, trash disposal, etc. and we were kept well informed about check-in, key collection and checkout so everything went smoothly.
The apartment is located in a quiet area and although walking to the city center is about 20min there is a LUAS stop really close.
