The apartment itself is good. The terrace is as good as advertised - the views are great. The location is fine - it's a bit of a walk to the tourist sites, but there is a metro stop just out the front door.
For a couple or a family with grown kids, I'm sure that it would be a good choice. But it was a challenge with our two toddlers - the elevator is tiny, which made transporting the stroller and bags inconvenient, and we were reprimanded by a neighbor and the host because the kids were too loud one morning at 8am.
