I've spent a lot of time in NYC but I had never explored Staten Island before, so I decided to check it out and ended up staying at David's place. I had a fantastic stay! Communication was easy, it's very easy to find, and the space itself was clean, comfortable, and really nicely decorated. The location is good too--it's right by transit and a 20ish min walk or super short drive or Uber/Lyft to the ferry. There are also some good places to eat and drink within walking distance, including a superb Sri Lankan restaurant and a pretty nice cocktail bar. I didn't have a car with me but street parking in the area looked like it'd be easy to come by as well.
Overall, I'd absolutely stay here again if I found myself visiting Staten Island again. And in all honesty, it's close enough to the ferry that this would actually be a pretty solid option for someone visiting Manhattan who wants to save money on accommodations. Realistically, you'd have to spend a lot more for a comparable place in Manhattan or the nicer parts of Brooklyn or Queens. Definitely a good value.
