Danielle's place is great. Brandt was very helpful throughout the stay. Check-in/check-out was very easy. The apartment itself is stylish, clean and very comfortable. Very comfortable bed, and a useful patio space.
There are two local subway entrances within walking distance from the apartment. (125th st). The red line entrance seems to be a lot more pleasant than the green line. It's fine during the day, but late at night, it can be a bit grim. Having said that, I didn't have any problems or issues with the subway.
There's lots to explore in the area, and it's not too far of a walk, if you want to head to the north part of Central park, and then continue exploring towards central manhattan/downtown etc. Otherwise, the subway and ubers are fine. (Although ubers can be quite expensive depending on the time of day). The subway is great value $35 for a week pass to use on the subway and buses.
