My friend and I only had a one night stay at Kells' apartment but it was great. Kells and Dave were so welcoming and friendly, and went above and beyond to make sure we were settled. If we'd had more time we would have loved to have checked out the guys play at a bar in the city, they sounded great while practicing at home.
The room was big and clean with a comfy bed, and the apartment is really well located. Would definitely check this place out again if I'm ever back in NYC!
