If this is available you need to book it!! Really cannot get a better location for the price. If you’re not dead-set on staying in the City or don’t want to break the bank, you will not find a better location.
Ferry is a 5 minute walk and it runs 24/7. We didn’t spend too much time exploring Staten Island, but there’s a cute little corner store right under your window, and a very nice outlet with lots of shops super close.
As far as PARKING goes, there’s a little lot literally right next to the apartment. The attendants are so nice and it’s $10 a day to park, but we only ended up paying $20 for our 4 night stay - I think it’s free on the weekends. Don’t expect a very official parking process, but an excellent one nonetheless!
We always felt very safe and really loved our stay!!
