It's been a pleasant stay. Close to Columbia (3 bus stops away) so I'd recommend anyone doing short term course there stay here. A very big space with clean sheets and fully equipped kitchen. Netflix and sports channels are available - we could watch Euro 2016 during our stay. Simon is very helpful, came set up in 15 mins after we requested the sports channel.
Noise is sometimes an issue bcz of the old floors of brownstone - rasps when someone is walking on level 3. But not a big problem.
