BEST PLACE TO STAY! This is such a great location, as long as you're not dead set on being right by a subway stop. You can very easily access the local bikeshare and bike paths, or just walk easily to a number of great places. AMAZING PRICE for what you get. Also, the building itself is relatively new construction and well maintained.
I also picked this location because it's right by the East River running track (and the East River running paths) - the track is still open during COVID quarantine. During non-quarantine times, you're also right by the big public pool at Hamilton Fish Park (there's a small pool just a block north on 10th st as well). There is also a building "gym", which has a Cybex model treadmill, stationary bike, and elliptical (with elevation!). There are no freeweights, though. The gym is right on the main floor, no lock.
You're nearby a ton of affordable grocery stores, and the kitchen is small but functional. There's a wide array of spices and condiments at your disposal as well.
The room itself is ground floor, but it faces the back, and it overlooks the "backyard" on the basement level, so there aren't people milling around outside your window, and it's overall very very quiet (for NYC). There were also a couple nice touches I appreciated in the room, like plenty of shelf space and a long clothes rail for your stuff, and the fact that the bed had one super fluffy pillow and one thinner pillow, so that you can choose your preference. There are blackout curtains, and because you're facing the courtyard, I also noticed that the room doesn't get very overheated during the day (there's an AC anyway).
Kaptan is also a great host himself - warm and friendly when you want to chat, but totally cool if you want some space to yourself, too.
