I stayed at Marylyn and Lloyd's for two weeks, and loved every moment of it. They are phenomenal hosts, the studio was exactly as described in the ad: cozy and comfortable and I had everything I needed. As other guests commented, Marylyn even supplies some basic groceries, which I appreciated so much. After a 9-hour transatlantic flight, two hours standing in line for immigration, and the ride from the airport, it was such a nice feeling not having to go out to get groceries.
The bathroom was shared, but it was no problem at all. What's more, it was always spotless. I had the feeling that as soon as somebody used it, it got cleaned.
The stop for the A and C train is just around the corner, and it's a quick ride to Manhattan. The neighborhood has a great vibe to it, and I always enjoyed coming home after a day in Manhattan. The Caribbean food options are great; I often stopped by the bakery on the corner to get a yummy Jamaican patty for $2 - that's pretty unbeatable.
Other people have commented on the neighborhood not being safe and people loitering. I can see how one could get this impression, but I think it's important to understand that it is a Caribbean neighborhood, where people are out in the street chatting with their friends and neighbors, but they are not bothering anybody who doesn't want to be part of it.
Of all my stays in NYC this was by far the best, and when I come back I'd love to rent from Marylyn and Lloyd again - if they have me, of course.
