We had a great time at Katrine's place and really enjoyed having two separate bedrooms (with very comfortable beds). Katrine was very responsive to questions and the key pick-up was very easy and convenient.
The location is very close to the A, B and C subway lines, which makes it quick to get into the main touristing area of the city. It is also a short 10 minute walk away from some excellent restaurants.
My one critique is that the bathroom layout has the shower only separated by the rest of the bathroom by a curtain, which means that the entire floor gets wet when one showers. This means that your feet get wet if you have to use the bathroom within an hour or so of someone having showered and also lends a bit of a musty smell to the apartment.
