Marius was an amazing host and helped us with every question and problem we faced.
The apartment is fantastic if you stay as a couple or with some friends, its location is great. If you're travelling with a child and a stroller like ourselves, you'll probably face some issues with the access via Metro, because most of the stops don't have an elevator. Our suggestion would be to avoid using a heavy stroller and take a baby carrier instead, or simply call a cab.
