We absolutely loved our stay at 12 E. Florida Avenue. We (myself, my mom, my sister, my brother-in-law, and their three small kids) were first-timers vacationing on LBI and it was the perfect place and experience for us! To begin, Lorraine (the owner) was INCREDIBLY responsive and helpful: before booking and then arriving, we had a number of questions given our lack of experience with the island and renting there and she responded patiently (and very quickly!) to each one.
The house itself is lovely and so well-appointed. If you have kids, the bonus is that there are lots of helpful things like a pack&play, baby monitor, tons of beach and backyard toys, a small baby pool, cups and cutlery and plates for kids, etc. We left a few things as well (e.g., a jumper seat for an infant).
We arrived and it was pristinely clean and had everything we needed. Like many/most homes on LBI, it's basically a block from the beach, which is insanely beautiful (and has life guards every day as well as daily visits by an ice cream truck!). It's a quick walk to a few places to eat and a quick drive or Lyft to many more. We loved running/walking on the bike path on Beach Avenue, which is the less-busy small road in between the house and the beach.
I can't say enough about this great house and overall experience with the owners! We will absolutely be making this an annual trip.
