We were a group of 10 people staying in the flat. We had plenty of space.
We spent most of our time out. Going back by foot from the docks is about 30min, so even without public transport it is possible to walk back. It's quite well located.
For light sleepers, it is an old building so you can hear elevator, people walking etc.. It is not in a night out area so it is not noisy outside at night.
We don't regret our choice, it was a nice and convenient place for a large group.
