The place is large!
Raviv is very responsive and he also has a friend that lives next door who will help out with things if you need help! I spent most of the summer without the AC (my choice) and when I finally decided to get the AC hooked up, Raviv had his friend come by to help/do it for me. Heat rises though, so even with the AC, I kept a fan on in the loft area for when I was sleeping.
The loft area is like 1/3 storage and then the bed and... a bench type area? It's a good size, enough space to walk around and several places to plug in things. The bed is an air mattress (I think?) but it's super comfy! Fair warning: I hit my head in the loft a few times... but I'm also clumsy. However, be careful up there! I think if you're tall, it might be a little more tricky. I'm only 5'2/5'3, so definitely expect to duck up there :)
It has all the general things you'd need (kitchen utensils, towels, blankets, etc.). It's conveniently close to a subway and a bodega that's open 24 hrs that has some of the more common household necessities. Generally, the building is pretty quiet, minus some people practicing their music, but even that wasn't much of a disturbance. Also, a random thing that doesn't seem to matter until you don't have it is good water pressure and good water heat. Both were great here!
Commute-wise: I worked near Lex Ave/5th Ave and it took me about 30-35 mins to get to work (when the subways were on schedule). You can get basically anywhere from the apt., you just have to take the L (which is the subway near the apt.) to a better "hub" station (like 14th St or something).
Neighbors are friendly. There's kind of a "hipster" vibe to the area. Laundromat(s) in walking distance. There's a restaurant/bar right around the corner about a block or so away that I only went to once (because I didn't decide to try it out until I was almost done with my stay), but I got a strawberry lemonade cocktail and it was really good! I also got a burger and fries that was pretty good.
If you ever need to drive, there's zipcar and car2go in the area. There's usually a car2go car within a few blocks. Car2go is cheaper, but I preferred Zipcar because I didn't like driving the little car2go car and it didn't have enough spunk for me. You can also uber/lyft, of course.
I'm probably forgetting something but overall, I enjoyed my stay!
