Stayed for 3 nights.
Good aspects: the location is really good and convenient.
The bad aspects: the window to the main street doesn't properly close, therefore you can hear all beeps and bangs in the evening and at night. The insulation is really poor - you can hear what your neighbors are talking; the mattress is mediocre - far from comfortable. Even though there is a kitchen you have to bring everything your own - at least you should expect some salt, sugar and tea to be present.
I don't consider myself very picky, but it seams that everything was done thinking like "that will do". And it is obvious in the kitchen and in the bathroom.
Suggestions: at least one socket with the EU 2pin plug would be really appreciated by guests from the main continent.
Next time I would look elsewhere.
