This ... was the perfect apartment. At least for me. Everything was according to or better as my expectations.
Bathroom - spacious, clean, large shower with high water pressure.
Bedrooms large and clean with great lockers/cabinets.
Living room spacious, bright and clean, as was the kitchen area as well.
Location is very close to the center, most places of interest in walking distance.
During night time comfortably low level of noise ... and in addition the windows are double-insulated.
The hosts have been helpful, supportive and really friendly.
So, the final verdict:
A luxury apartment with a 5 star managment (the hosts).
They will see me again, soon
