Starting from the negative aspects: the room is under the street level, it means that is a basement. The room environment is extremely humid, the air inside can have an unpleasant smell and your items such as swimsuits and beach towels won't dry off but will become even more wet. Furthermore the room is quite dark, there are only three very small windows and a door that brings to the garden.
However, the positive aspects are that the room is quite big and very clean and the shared kitchen is well equipped and clean.
The communication with the hosts is excellent, their responses are rather immediate and they are very helpful.
The position is excellent too, it is just few minutes walk to ferries and bus stops.
