Alex's flat is well located and in a very cool area for authentic neighborhood exploring. The flat has everything necessary, Alex even left an extra prepared bed out for us even though we didn't need it!
The only downside is that the fridge is really noisy and right next to the bedroom so we had to pulled the plug out overnight (it was empty and we didn't use it)- slightly inconvenient if you're planning on using it.
The L line is super convenient and gets you around Williamsburg and Manhattan quickly, there are shops, restaurants and bars around.
