I found the check in very stressful. They suggest check in is only between 4pm and 8pm and will charge extra outside of those hours. They also charged us 20 euros cash for checking in on a weekend upon our arrival. This is part of their usual policy but they should just increase their fee on Saturday and Sunday on the air bnb app if they want to charge more to check people in on the weekend.
In terms of the apartment it was a good place that was clean and spacious. You can not open the windows so it's
a bit stuffy.
The location is great and it is walking distance to many bars and cafes.
