I've stayed here twice and both times what an amazing experience!
I first rented a room when I had an unexpected business trip in New York in 2015. The second time, I came back with family and we rented two rooms/whole apartment while explored New York.
The location is in a vibey part of Upper Manhattan, with lots of interesting locals and minutes from the subway stop - I was in Times Square in 20 minutes. Pierre can also arrange airport transfers and cabs if you're that way inclined.
The rooms are actually better than they look in the pictures - well decorated and spacious with lots of light. Everything was spotlessly clean, with all the add-in's you'd expect (a mini fridge, tv, reliable wifi, coffee supplies) -there were even little chocolates on the pillows and little toiletries in the bathroom.
Pierre is an incredible host - unobtrusive, friendly and helpful with lots of advice on what to do/see, it's like staying with family or friends, only better because you get the comforts of a hotel too! We landed up spending an evening with him drinking wine, eating cheese and talking.
Definitely stay here!!
