We've been to Old Orchard Beach many times, and we enjoyed our stay at this condo very much! The group was me, my 14 year old daughter, and two of her friends. The girls took the loft bedroom and I used the bed in the walk-out basement.
The place is great for a clean, convenient place to lay your head while enjoying Old Orchard! It's about a ten-minute walk from the beach, but that means it's far enough from the train tracks that the train doesn't wak you up. (If you stay right at the beach, you will hear the very loud train at all hours.) The kitchen is great, with space for up to six people to sit and eat. (As with most short-term rentals, if you need sharp knives for cooking, bring your own.)
Be sure to read the description so you understand things that might not work for you. The only bathroom is downstairs in the walk-out basement bedroom area, and to get there you have to go down a very narrow, metal, spiral staircase. This was not a problem for us, but this condo would not be a good choice for anyone with mobility issues or challenges with tricky stairs. Also, as others have mentioned, both bedrooms are all open in one way or another, so you hear everything going on. Again, not at all a problem for us at all, but do be aware.
Overall, we loved our stay! We met owner Moira once briefly as we were checking in, and she was lovely. Thanks for a great couple of days!
