Really loved my stay at The Mermaid & Alligator! The property is beautiful and in a very convenient location — easy to walk or bike to just about everything. You can even rent bikes from the property. The hot breakfast every morning was amazing, and I appreciated having snacks and drinks available all day. The only small downside was that the room I was in, the Sun room, was pretty small, but the balcony was awesome and made up for it. Finally, the staff were all super kind and friendly. Overall, a great stay and I’d definitely come back!

The property is a beautiful oasis and the staff kind and accommodating. Good location if if you don't mind walking a little and easy to get Uber if preferred. Breakfasts were exceptional and our room/mini-cottage was beautiful! I highly recommend this property and hope to be back on our next visit.
