The flat was clean, very nicely decorated and amazing location right in the middle of the city centre. We walked everywhere and found restaurants, tours and shops at walking distance.
Be aware the flat is in an old building with no lift and has a few stairs. My 5 years old son was a star and didn't complain once but I would definitely be inconvenient if you have a push chair or health condition.
The beds were comfortable but very noise which was annoying as I wake up very easily. The WiFi didn't work during our stay. We had data so didn't matter much but couldn't watch Netflix or use Alexa (that we brought from home).
Overall very good experience but a bit disappointed with noisy beds and no WiFi.
