So this is what AirBnb used to be about and should still be. An actual Brooklyn apartment with people living in it in an actual real neighborhood with local people living in it. Admittedly I was on an extended stay, but it felt more like a flatshare than an AirBnb - although you would hardly know that your flatmate - who is great by the way - was in most of the time. The way the rooms are laid out, you are the other end away from their room. The room is spacious, with a desk to work at, and plenty of clothes storage, a big comfortable bed. No, it's not a gleaming anodyne hotel room. It's got stuff in it, pictures on the walls, books on shelves, bits and pieces knocking around. In short it feels like you are in a home in all the best ways. It IS at the front of the house and Nassau Avenue is definitely a well-used road, so if you aren't used to traffic noise you might find it an issue (especially on a hot NYC night when you want the windows open). But I have ear-plugs with me for that reason, and haven't put them in once - I actually like the sounds of the city going on out there. There is space to lay out a yoga mat, if that's your thing. And there's even one here I was able to use.
There's also a shared living room off your space (which is curtained off - not a door - but that is so NOT an issue) but to be honest it has basically been mine to use, with my flatmate hardly using it at all. Think I've only seen her in there once in a month.
Kitchen is not huge but got everything it needs - nice big fridge with your own space.
Bathroom does what it needs to.
The neighborhood is up and coming but right now totally unspoilt, unlike its trendy neighbor Williamsburg, which you are in easy walking distance of. It's predominantly Polish and a very local feel, with people just getting on with their lives. There's a great park just across the way for sunny evenings, a convenience store below, and a laundrette opposite.
There are also plenty of bars and cafes around - just not huge trendy 'nightlife' ones. Yes it's 8 mins from a subway but it's a (safe at all times) pleasant walk and you can pick up stuff you need on the way home.
So basically I would thoroughly recommend Liz's apartment for you to stay in.
If I am lucky enough to get another visit to New York any time soon, I will DEFINITELY be coming back here.
