My wife and I plus our two sons (21 and 16) stayed in this apartment in August 2019. We had a very positive experience. The space was well appointed, not at all sterile like you might find in some aprtments, it was warm and inviting. There was ample space for all four of us, we could hang out together or each go to a seperate area if we needed "space" after a long day of sight-seeing together. I especially enjoyed relaxing on the terrace with a beer at the end of the day.
While the weather was rather warm, the AC functioned well, it quickly made teh aprtment comfortable soon after we switched it on when we returned.
The location is excellent: 15 minute walk from central train station, 10 minutes to the old town square, tram stop a few minutes away. Lots of local restaurants and pubs as well as bakeries and small stores to get the essentials.
The one thing to note is that a few of the evenings (Friday\Saturday) there was a fair amount of noise from groups in the streets leaving the bars. It's not the bar in front of the building, seemed to come from around the corner.
All in all, a great stay and we would certainly recommend it to all to stay there.
