I staid at Rosalias apartment for little more than a month.
Rosalia has a clear a fast communication and some rules that has to be followed. The room is nice and the bed is comfortable. If your are taller than 1.80 the bed is a bit to short. But I slept every night very good! The kitchen has every think what is needed for preparing dinner. The freezer is from time to time a bit full. But it was every time possible to find a place for my food.
I recommending Rosalias apartment and also the area of Charlestown.
