Awesome place to stay !
Pros: ease of building access via keypad. Though entrance is shared, one can come & go in a way that makes it feel like you have the entire apartment to yourself. Very quiet apartment and bedroom location. Great bed. Fantastic bathroom & shower. Room has top-notch AC. Extremely clean. Prompt replies from host to questions. Subway is about 3 mins walking distance from apartment. Felt very safe and serene in apartment- highly recommended for solo, female travelers.
Extra thoughts: don't bring bulky or heavy luggage with you. Access to both guest rooms and the apartment is via stairs. The main staircase in the apartment is narrow and I would imagine difficult to maneuver large or heavy luggage up/down. ( not to mention, it will echo. The apartment isn't carpented) Subway location is awesome for Manhattan. You can get to Penn Station and Port Authority in no time. If you want to visit another borough, it will be a lengthy train ride. This is probably fine for tourists who are just visiting but if you're from the city or a regular visitor and you like to go to Queens/ Brooklyn often, it's a bit of a hike on the metro.
