I stayed at Buh's house in Jersey City for about 1 week in October. There are many positive things to say about this house and I will begin with the location.
The house is located off Bergen Avenue, which can lead you on foot to Journal Square in about 30-40 minutes. I chose this house because I have a friend who lives near Journal Square, but if you want to go into Manhattan, it takes an hour, at least. So that is something to bear in mind. (From Journal Square there is an underground train called PATH which leads there. This is not part of the NYC Metro.) However, I quickly got used to the public transport, and was still able to have full days out, taking in many of the best sites around Manhattan.
In Jersey City itself, there are several gems nearby, such as Liberty State Park (half an hour by walking east) which gives fantastic views of the Statue of Liberty, as well as Caven Point to the south of that - which is a beautiful, quiet nature reserve overlooking the bay. Along Bergen Avenue there are many convenience stores with affordable groceries and snacks, as well as a few restaurants nearer Journal Square. There are buses around the area and to Journal Square, but most distances felt perfectly walkable for me.
The house itself is quiet and feels very cosy, and the living room is both functional and well-decorated, with pictures of inspirational figures on the wall - a reflection of Buh who is himself a fantastic guy! The kitchen is perfect. I used the stove, utensils, microwave and sink. Those shared areas do not have windows BUT are nonetheless very cosy, with some nice lamps. The bedroom, however, does have a window, as well as a desk, with strong WIFI connection, so I was able to have smooth video calls from there. The bed is comfortable, and the bathroom is perfect, with a warm shower, mirror, sink and toilet.
Finally, Buh is a really positive guy and a great host. On some dull/rainy days I stayed in and had some really insightful conversations with him about a variety of topics which definitely made my stay worthwhile! He is communicative/responsive and is also very helpful - he gave me some advice on public transport and even helped me print my boarding pass on the morning before I left! All in all, I had a brilliant time there and recommend it to anyone who wants to see New York and stay in affordable accommodation.
