I would highly recommend Karen’s place to solo travelers looking to get away from the hectic areas of NYC while still staying a train ride away from almost everywhere. Although if you are planning on traveling to Times Square or further into Manhattan, it can take well over an hour even during off peak times. Also Avenue P Station is almost directly behind the room so I would recommend bringing earplugs or headphones if you are a light sleeper.
Karen was very hospitable upon arrival and was always available for questions or queries. The place is a lot larger than most in the city and is very clean and comfortable.
The area around is quiet and quant and doesn’t have much of a night life but has plenty of food options around, and the station is very close to the house so it’s very easy to head into busier areas.
Overall, an excellent stay :)
