Felt really safe in the building, metro station is just outside the building so transportation was easy to figure out. There are places close to eat.
As far as the actual apartment it had plenty of beds and she provided towels which was great because we forgot some of our towels and toiletries at home. She provided excellent instructions as to what was available in the building and how to access it. We didn't feel like we needed anything while we stayed there. The kids loved the Kureg she made available because the enjoyed making hot chocolate on the cold mornings.
