Angelika's apartment is a lovely, spacious, clean spot in Bed-Stuy. The G train is quite close, and from there you can transfer to any number of other lines to get into mid- or lower-Manhattan or the rest of Brooklyn and Queens fairly easily, if not the quickest (door to door it took us about 35 or 40 minutes to get most places we wanted to get in Manhattan, sometimes longer).
The apartment itself is really nice, lots of room, with a lovely courtyard out the back. If you need the second bed for more guests, the sofa converts, but it's just a jigsaw of sofa cushions you end up sleeping on, and we weren't provided any extra bedding for this, so that was a little disappointing. It's not the most uncomfortable sofa bed by any stretch, but it's certainly not equivalent to another real bed. We also found the wifi signal to be weak at times, and phone reception in the apartment itself is also poor. The hot water would run out at peak times or after maybe one and a half showers, and the kitchen doesn't really have all the utensils and crockery you'd want to cook a full meal.
In spite of these relatively small blips, we did really enjoy our stay. It's a comfortable apartment, and really large compared to what you might expect for New York. In the future I just might look for a better location.
