Marc's place is so wonderful! It is quiet -- perfect for the person who wants to experience the rush of NYC in limited doses. I stayed at Marc's place for 10 weeks, and it was such a relief to end my days up in calm(er) Washington Heights after a full day of activity in midtown.
The A train is quite close, and good grocery stores are just a few blocks away. There are lots of restaurants nearby that stay open late, so even walking alone after midnight, I felt very safe. Marc was a wonderful host; he replied quickly to my questions and was very welcoming. The doormen are also super nice and greeted me by sight every day.
Marc's place has really calming vibes -- that beautiful tree by the window, a perfectly neutral aroma (hard to accomplish in older Manhattan apartments!) ... just lovely. There is no microwave in the kitchen, but there are plenty of pots and pans and a great oven, so I didn't miss it. I would happily stay here again!
