We stayed at Katarina's place for a wedding, and it was perfect. The venue was only a quick car ride away so the location was ideal. The neighborhood was cute and family oriented. Lots of shops and groceries within walking distance, but not at all touristy. Plenty of places to eat, and if you want a bar there are a few within a 20 min walk but no loud clubs nearby to annoy you! It's fairly quiet at night, but hey this is Brooklyn, so don't be surprised by a loud truck or something early in the morning. We had earplugs and slept like babies.
She's very serious about the "no guests" policy, but we didn't need to entertain so that was just fine with us. The space is cute and functional, getting in was easy, and Katarina was very responsive with her communication.
If you need a place to stay in Ridgewood, this is an excellent value for two people.
