Viktoria's place is a bargain for Manhattan which is why we decided to stay there. It is in a prime location on the east side and a few blocks away from the Q line. It is near many restaurants and Central park, so there is a lot to do with minimal travel distance.
I would say the only downfall about the place is its design and loss of privacy. The only bathroom is in the only bedroom, and given that you share the apartment with Viktoria it may be inconvenient (wasn't really the case during our stay). The shower is also in the kitchen given the small size of the apartment. Otherwise everything was as expected.
I would say this place would be perfect if it wasn't a shared space, but given that it is shared you do lose some privacy given the small space.
Overall, Viktoria is a friendly and lovely host, she does have some late work hours which may or may not affect your sleep. We did not find it to be too problematic as we often returned late at night. We had an enjoyable stay and a great trip!
Thanks
