Glenn was really responsive and kind both before and during the stay, the communication was always quick and most of the time clear, even though I think that the in-chat translator doesn't always do the job perfectly.
There were some problems with hygene: the apartment smelled a bit like mold (and I found some on pots and on the bathroom ceiling); the sheets were not clean.
When I asked him to change them he immediately sent the housekeeper, but not all the sheets were replaced and the new pillow covers still seemed not clean.
