We had problems with our check-in: I got an email letting me know they had changed me to a different location on the other side of town a few minutes before I arrived at the first address.
When I called them to understand what was happening, they told me the apartment I had booked a week before was not available for all the dates I had booked it for, and that is why they changed me to a different location on the other side of town. The thing is: we were in a group of three, and the second apartment only had a bed for two.
After a stressful hour between not being able to enter the apartment and the contact with the host, they finally managed to get us to another apartment in the building, just like the one I had booked, and it all went smooth after that.
The apartment is great, very comfortable, and the location is quite good as well. Besides the check-in problem, everything else was excellent.
