Katja place was quaint, clean, and was a great place to stay for our trip to New York. It was easy to get a hold of Katja if we needed anything or had any concerns.
It is a 5 min walk to the L-train, and the commute on the L-train to Manhattan takes 25-30min. It also took 20 min to get to Williamsburg on the L-train.
The neighbourhood was noisy on the weekend and some weekdays. If you are looking for a quiet place to relax you will be kept up by a neighbourhood crowd playing music.
