The apartment is located in a very convenient area, a little bit out of the very center but at same time only at 4 metro stops to the cathedral.
It was very clean and self check in is extremely good.
We didn't meet but Michael was very promptly reacting to our questions and he was nice to allow us to check out in the afternoon.
The apartment is not big, so it's ok for two persons for short staying.
All in all for sure a positive experience.
