We absolutely loved Ben & Christina's apartment. It is modern, very clean and tidy, with sufficient space in your own room; we felt very at home here. We practically had the place to ourselves during our stay, as Ben was out of town, though we did very much enjoy Christina's company too when she was home.
The subway is about 5 minutes or so walk from the apartment, with many restaurants, takeaway, deli's and convenience stores along the way. We didn't have any issues walking in the area late in the evening also. Overall, we were very comfortable at the apartment and we appreciate their hospitality, would definitely stay again!
