We stayed in this apartment for a weekend with a group of friends (4 couples + 1 baby). For the size of our group, the apartment was perfect! Large common rooms plus enough bathrooms & toilets (3 in total). The apartment is nicely located and you can reach the city center in 10 - 15 min by foot. WI-FI works flawlessly. Being there in the beginning of December, we can't say that we were ever cold in this apartment - the heating worked like a charm.
The hosts work in a really professionalized manner and even went so far as to provide some toys for the baby when they heard that we had one with us!! 5/5 can absolutely recommend!
