I don't know where to start :)
If I should evaluate our stay in NY giving some points from 1 to 10, I would give 11. Everything was great, Graham's apartment & our contact in particular. Situated two steps from main "attractions" and useful places:
5 minutes from metro station & Murray Hill Dinner where we had our breakfasts ;) (there were also quite nice small restos) , 2 min. from Starbucks and others coffees.. 10 minutes Empire State Building, 15 minutes Grand Central Terminal, 25 minutes Rockefeller Center & Times Square, 31 minutes MoMA etc.
It was really a perfect location. In the same time it was calm so after whole days of walking, we had much pleasure to have a rest there.
The apartment was big enough, very comfortable, with much light and super view from the terrace. Clean and with everything you can need to have your stay enjoyable (BTW, great music in the radio!). Graham was very kind and helpful and the contact we had was very, very good.
He left us useful information about facilities around (laundry etc.) and we stayed in contact during our stay. And Carsena, his housekeeper was soon lovelyyyy... :)
Thanks for everything !
