The apartment is excactly as described. The hallway, kitchen and living room are not seperated through doors, but that was no problem while cooking (good exhaust duct). It seems like a big open room. In the morning you can eat with sunlight in the livingroom, that was great! Eventhough the bathroom has no window, there is a really efficient exhaust duct that quickly interchanges used up air.
When you stay longer it is good to buy a 7 week subway ticket (33 dollars), you will need it.
There is always quick help if you have questions or need something even when Mark is travelling!
