This is a spacious place with a stylishly modern feel to it. You can use a bus or an uber/lyft to get to the Flatbush Station and connect to the rest of the subway. If you choose to uber/lyft, then travelling from Eli's place to the Brooklyn Museum or Prospect Park takes roughly 45 minutes. Or if you have your sights set a little further, then it takes a little over an hour to parts of Manhattan.
If you are trying to explore the inner areas of Brooklyn, then Eli's place is a great find. Obviously, if your goal is to explore Manhattan, then you should consider booking a place there, but the fact that we chose to book Eli's home anyway should say something about its price point and comfort. If you're having problems with getting the key, then Eli's neighbor will help you out -- but she will first ask you for the code that Eli sends, so be prepared for that. Anyhow, it was a pretty good experience for us all! I would definitely recommend this place, especially if you are travelling with a larger group (3+).
