David's flat is great and just as the pictures show. It is quite deep in south Brooklyn and can take a bit of planning to get into Manhattan or Williamsburg however the subway is about a 10 minute walk, which will take you into Manhattan in about 20 mins (be sure to get the fast train if you can) and there's the option of the bus into Williamsburg, which again is about a 10 minute walk to the stop we went to and then another 20 min ride (plus a bit of a walk).
The area is generally fine and understand that it's on the up and probably still a bit of a way to go before it reaches the lofty heights of Prospect Heights or Williamsburg.
There aren't too many options for late drinks that we knew of so we ended up either staying out later or coming back earlier to prep for going out again. It's not really the sort of spot to drop in and out of.
Having said this it has to be said that we did enjoy discovering a new side to Brooklyn with the hide away cafés (we liked Le Paris Dakar for great pancakes) and the amazing Hothouse Chicken restaurant (just across the road) for the most authentic fried chicken experience we've ever had! Top notch craft beers to boot! Actually think this was one of my favourite restaurants we went to throughout the entire trip!
Also has to be said that David was very accommodating and although we did not get the chance to meet he was always available through text or messaging on the Air BnB app. Great host and would recommend the flat for the adventurous!
