I stayed at Jakob's for a week and the Studio has everything that you can need for a few days or a few weeks.
Location. The apartment is 2 blocks from the tram stop, there are a few restaurants around and there is a supermarket also a couple of blocks from it.
Cleanness. The apartment is clean and in a very good condition.
Quality of Sleep. I slept pretty good, good temperature and it is actually pretty quiet (with the exception of a neighbor that was celebrating his/her birthday)... Bed is also comfortable
Equipment. As I said, it has pretty much everything you need.
Overall. It is a good place to stay as a single traveler or a couple.
