I think this is the best place we've ever stayed in OOB - and we've been going there for many years.
Martha and Marc were there to welcome us when we arrived, and we felt at home as soon as we unloaded the car. They've thought of everything - we could have come with clothes and food and not needed another thing for the entire week. Linens, towels, beach towels, a great, rugged cart to haul stuff to the beach, air conditioners in the bedrooms (that actually work), fans throughout the house for every room, wifi, washer & dryer - just awesome.
I know it sounds silly, but I so appreciated being in a cottage that didn't look like an explosion at the Christmas Tree Shop (if you're regular visitors to OOB, you know exactly what I mean). Tastefully decorated, and something as trivial as having matching dishes and silverware made me feel like I was in my own home - just in a much better location.
Speaking of the location - jackpot! A 5 minute walk down to the beach, 10-15 up to the pier, 5 or so to the mini-golf. Close enough, but just far enough away. We went to the OOB House of Pizza right up the street, and it was great. No need to go all the way up to the main drag.
I would second what someone else mentioned below - the bed in the master is very, very firm. If that bothers your back, you might want to bring some sort of topper (non-latex, of course - allergies, you know) or plan on dragging in one of the twin mattresses from the other room, which is what I wound up doing.
I would definitely come back to this property for another vacation. Give it a go, you won't be disappointed!
