We had a great time at Samaa's. The apartment is just as described and a good place to start exploring NYC. Quiet enough to get some peace in the evening, but close enough to subway, shops and restaurants. Carroll St Station is just at the end of the block, maybe 200 mtrs. If you like greek food try Avlee, it's quite cheap and we really loved it.
The apartment is in good shape and has everything you might need for cooking. The restroom is spotless. The mattresses in the bedroom are really good, the sofabed in the living room maybe a little too soft for big people like me. For our daughter it was ok.
We didn't manage to meet Samaa in person, but communication by cellphone was easy and she managed all our wishes to our satisfaction.
For 2 people I highly recommend this place.
