At Xenia's place, what you see is what you get - except maybe for the aquarium, but we didn't mind not having that! :-) The room and, more importantly, the bathroom and kitchen, are clean and in perfect working order.
Though we didn't see Xenia during our trip until the very end (due to conflicting schedules), we had no troubles finding everything we needed as Xenia was very helpful through text and online messages. The house and the other roommates were very quiet and peaceful, likewise for the neighbourhood.
In short, for those who don't mind travelling from and to lower Brooklyn each day (tip: read books on the subway), this place has every advantage you'll need for a very good price - even a very nice breakfast/brunch place around the block, Parlay. Would recommend!
