My boyfriend and I spend two weeks here and really felt at home. We both work from home and this worked out great as well. The flat is spacious and with the amazing windows, a lot of light comes in. It is a bit chilly in winter time, since the isolation isn't the best but nothing some thicker clothes can't solve.
Be aware that you have to pick-up the key elsewhere, which isn't great in my opinion but luckily, you don't have to drop them off there as well.
All in all, I really recommend the place - also for long-term stays :)
