The location is amazing – lots of restaurants, cafes, bars right on your doorstep, as well as access to multiple metro lines. If you have suitcases you'll be pleased to find that it is on the ground level.
We didn't have any issues with the wifi and I actually worked from the apartment for a few days.
There was only one set of keys so if you're travelling in a group and want to separate, you will need to coordinate between yourselves.
