I stayed alone in the apartment and it was actually too big for me :) But I can't really complain about that. What I most appreciated about the place, were the big windows as I like to have as much as daylight as possible. The sunrise might wake you early in the morning as there are not many curtains. However, when sitting on the balcony, I did not get to do it with the sun during the day. Maybe it'll reach the balcony in the evening which was the time that I spent outdoors in the city. I mainly used the kitchen space as it is well equipped and a cozy area. The wifi was the worst that I have ever experienced during any of my trips, and I have travelled quite a lot. I was working remotely and the bandwith did not enable me to have Zoom calls neither download even the smallest files, even when I was sitting next to the wifi extender. Instead I had to buy additonal mobile internet. So if you're working remotely and need a stable connection, consult with the host as he might have a stronger wifi extender as a solution. It was a huge problem for me, I ended up in the cafteria, as the wifi was much better there.
I strongly recommend to keep in mind the floor that the apartment is located on. I personally didn't have any problem climbing up the stairs, but if you have heavy luggage or you tend to get out of breath easily, the place is not for you. If you leave the apartment for daytime, leave the window open as the piping brings a strange smell to the apartment. The neighbourhood is pleasant. The bus stop is right infront of the house. One bus stop (or 4 minute walk) away is the U-line which conveniently takes you everywhere. The groceries close at 8pm (completely closed on Sundays) but right on the corner there still is a store which you can get the basic stuff.
