Thanks to Majar, we enjoyed our staying in his apartments. The room is really huge for NY, everything is convenient and clean, comfortable bed and good internet - what else do you need?:) We didn't use the kitchen but it seems there are all appliances you need and a big table with chairs.
The other plus is that it is really close to metro station and there is a DD near metro so you can start your day with a fast breakfast during your trip to Manhattan via ground line (as the metro line is above the ground, it is awesome in sunny days).
Well, come to Majar, check it yourself ;)
