Nautilos is a very friendly hotel in Capurganá, in the Chocó region, bordering Panamá. If you want to travel into deep Colombia you have to leave behind your expectations that you will have incredible internet connection and five-star services. Rural and isolated regions in Colombia, the most beautiful and scenic regions by all accounts, suffer from chronic infrastructure problems. So you should be warned.
That said, Nautilos does an amazing job to please the guest and the staff goes to great lengths to make sure your stay is as pleasant as possible. They are helpful and always pleasant. I stayed at the most basic package, so I can't really talk about the food or bar service, but the swimming pool, access to the beach, jacuzzi and steam room were all excellent. If you have travelled, as I have done, through the mountains and jungles of Colombia, with all the infrastructural problems of the country, and stayed at really basic and run down places, you will appreciate the luxury of this place (which in New York may be basic, but hey, this is Chocó, the poorest region in the country, although a true paradise on earth) and you will appreciate the effort the staff and management put to keep the only hotel with all-night-long electric service in Capurganá. It is not cheap for Colombian standards, but then again, you have to put everything in context...
Will I go back again? Sure. I loved Capurganá and its jungles, full of monkeys, toucans and sloths. The weather was fantastic and the beach is unbeatable. The staff are nothing short of adorable. I made great friends -be open to hang around with locals help a lot. If you want a five star hotel, stay in Medellín. If you want to venture into deep Colombia, be prepared to give up one or two luxuries.
Oh, and I do concur on one thing with other reviewers: Josefina's restaurant just beside Nautilos, is truly amazing, one of the best costena cuisine restaurants I've tried. Nothing fancy, but the flavour... simply divine!
