I had a great stay at Rosaly's place. The location is great, in a quiet and safe neighbourhood, but you have everything close by: supermarket, cafes, Central park in 15 min walking, buses, subway. The apartment is not big, but it's charming, has a historic feel and has all the necessary amenities, including all the cooking utensils and even spices. You'll hardly ever see or hear neighbours in the building.
Check-in was smooth, Ro waited for us, even though it was Sunday evening, and gave tips about the area.
The walk-up is not that bad, although you have to take it into account if you are bringing heavy luggage.
All in all, good place to stay
