The apartment location is excellent: central, yet very quiet. Everything that we wanted to visit inside the city was easily reachable by foot. And despite having plenty of bars and restaurants nearby, the apartment is perfectly quiet at all times: zero traffic noise, loud bars, etc.
It was also super well equipped and very clean. We weren't missing anything during our stay.
Check-in was straightforward and the host very responsive in the process.
The only downside of the apartment is that the amount of natural light it gets is quite low, due to its position in the building. This was fine for us, as we stayed for a week and were mostly out exploring the city and surroundings during the day. But it might not be ideal for longer stays (e.g. remote work).
Overall, I would highly recommend this apartment for visiting the city!
