The constructions nearby weren't as bad as I read in terms of noise nuisance, but sadly provoked a massive water infiltration in the living-room. The host who is very responsive and comprehensive accepted a refund. Just make sure the issue is fixed before you book.
The flat itself is beautifully furnished and well equipped. The living-room is really huge in terms of surface and volume, which comes with the drawback of being quite cold (even in mid-May): indeed it's not very well insulated (its windows are a bit old and single-gazed) and the AC unit, standing on one corner floor, is not powerful enough to heat up the whole space.
The bedroom, however, doesn't show this problem as it's much smaller for the same type of AC unit and has triple-gazed windows.
