I stayed at Sophia's with my mother for a week as we explored New York city and I cannot say enough great things about it. First, Sophia is super accommodating and easy to reach. This eased our minds as we were travelling from different areas of Canada and coming into different airports. Second, she takes the time to checkup on you during your stay to make sure you are enjoying yourself and have everything you need. This was really appreciated and thoughtful. Third, she recommended local restaurants and places to check our around the apartment. I highly recommend you follow these recommendations as it turned out to be some of the best food we had all trip. Finally, we loved this area Brooklyn. Although we split our time between Manhattan and Brooklyn is was really nice to come back to this apartment after a day being swelled up by crowds and noise. It was quiet and calm in the evenings and the people were helpful and kind. If you are commuting into Manhattan the subways (C, J, Z) are very close and either take you directly were you want to go (we mostly stuck with the C line the entire time) or connect to main transfer hubs.
All in all, Sophia's was wonderful and we would recommend it to anyone visiting New York.
