My boyfriend and I stayed with Susan and Marco over Easter and our stay was very pleasant.
Their flat was ideal as it wasn't far from Manhattan (15minutes by subway ) and Williamsburg in general is a cool neighbourhood with lots of funky bars/restaurants nearby.

Their flat was nicely decorated and furnished with a huge bed that that was incredibly comfortable to fall into after a long days walking! Regarding the bed, complete comfort is guaranteed!
Their flat was always warm and cosy and we had our own privacy.
What we liked about Susans flat was that we couldnt hear any outside noise.

To conclude I would recommend this flat to anyone who doesnt mind being 'a little outside the centre ,' and for those who wish to use it as a place to sleep and go. Due to the fact that the couple work from home, the living room forms part of their office area which may not suit some people.
Nonetheless this did not affect us as we left early morning and returned late at night!
