We had a great stay at Arubiana Inn.
The rooms are outfitted with al lot of stuff, from a cool box to an extra set of beach towels. A comfortable bed, a well functioning A/C and fridge, friendly personnel, a refreshing pool for that cooling dive after a day at the beach and Wi-fi included are all plusses in our book.
Of course the beach is a bit further away from the location of the hotel, but to experience Aruba fully one should rent a car anyway, so that wasn't an issue for us; this way we visited another beach every other day :)
Also the Super Plus within walking distance is a nice addition!
Last but not least: the small scale of the hotel keeps it cozy and stimulates a nice little chat with your neighbouring guests!
