Good place, the neighborhood is enough safe(sometimes we met not very good-natured people, but this is how it can be everywhere in New York). Near you can find a lot of supermarkets, the apartments are located near the subway stations. The place was almost clean, some towels had stains and the carpets were not really clean. The other things were perfect.
There is a rooftop On the 35th floor, really amazing (and it is for free)
So we really liked our stay at Sonder;)
