Two friends and I stayed here for 11 weeks during the summer. In terms of location/convenient access to the subway, this was a great place to stay. We were about a 3 minute walk from the B/C lines and a 10 minute walk from the 1. The price was also cheaper than many other long-term properties we looked at on Airbnb.
However, part of the reduced price likely relates to the minimalist set-up in the apartment. This is an ugly apartment, for lack of a better word. The furniture is old and looks like it was picked up from various garage sales. There is a clear plastic shower curtain in the one shower and gaps in the moldings that have been stuffed with steel wool. We had issues with water bugs (supposedly a distinct species but they look a lot like cockroaches) when we first moved in and continued to see other creepy crawlies during our stay. The apartment also didn't appear to have been professionally cleaned before we moved in (i.e. Hairs in the shower, duvet covers did not smell clean, floors were dirty when we Swiffered).
These things are mostly cosmetic. If you don't mind roughing it a bit, you'd likely be fine. For my friends and me, this was mostly a place to sleep and shower and I thought it served that purpose. Also, the free laundry in the building was a nice perk.
Amy, the owner, was responsive when we contacted her with various issues. The issues may not have always been addressed as directly as we may have liked but I never felt like Amy was trying to duck my emails. For instance, my one roommate had an old AC unit in her room that wasn't working. When she contacted Amy about it, they installed another AC unit, which also wasn't new. The replacement unit also had to be repaired once following that but eventually was working.
In sum, our experience here very much felt like the owner was looking for the cheapest way possible to make this place habitable. If you can handle living with the bare essentials and are looking for a relatively cheap place to stay in Manhattan that is centrally located, I'd recommend this property.
