We stayed at Thomas' place for two weeks and we liked our stay. Apartmant is exactly as described. Bathroom was very nice and shower has a great temperature/pressure. Bed was very comfortable and sleeping quality was superb (quiet, dark, good temperature). Table is big enough to fit two persons working (we worked during our stay). Temprature control was awesome and that includes floor heating as well (we stayed in October). Location is okay, though you need to walk 10-15 minutes to reach supermarkets or central part. However, the neighbourhood seems to be very safe and quiet. Check-in and check-out instructions are clear.
One thing I want to mention is internet speed. It is 12-15 mb down and only 1mb up, which was not enough for us to work. However, host was responsive, and provided us 1-month sim card with better internet (30/10), so this worked fine for us, but as this was only a temporary solution, I think this should be mentioned. Thomas does try his best to help us, so it was very kind of him.
Another thing that we personally didn't like is that apartment is quite dark during daytime. It is on the ground floor and overlooking small backyard between buildings, so there is no sunlight at all. But maybe we're just being picky.
Overall, we had a great stay.
