Well... you usually don't expect to be waked by rain falling on your bed, and then spend part of the night installing buckets below leaks and absorbing 10 liters of water on the ground.
That explained the smell of humidity when I first came in.
I was fortunate that the rain did not last too much.
The manager/owner did not seem alarmed by the problem, and did not offer any compensation.
Plus side : good location, quiet (opens on a small inner courtyard), 4th floor so remains clear enough. In an old wooden building, quite nice.
Minus side : small and expensive for this range of price, needs serious refreshing and repair (the leak when it rains was apparently known as there are marks on the wall and on the ground). The bathroom is tiny and unpractical (the sink is barely the side of a hand wash for toilets).
