There were two of us and we enjoyed our stay in the Maxwell/Oistins area. The apt is close to a couple of nice small beaches, and walkable to shops and Oistins. The better restaurants are a bit further up the coast in St Lawrence Gap, but there are many taxis if you use the app.
The apartment itself wasn't as good as we hoped. If it is "newly renovated" now, it must have been awful before. We had one apt each, travelling as single friends. The advertised one could do with a proper clean, in particular the bathroom where the sink, mats and floor clearly hadn't been cleaned. As such the two apts were expensive for two people, but I appreciate they would be a lot cheaper for four people sharing each one.
One plus - excellent air con in the bedrooms, a fan in the main room, and screens on windows. A nice balcony though no view to speak of.
We didn't meet the host at all, nor anyone else, but he responded quite quickly to emailed queries.
