I live in the condo I own in El Neptuno. Very conveniently located, a couple of short blocks to center of town and beach, well managed (now, not so up to last January), nice pool, friendly people. Has own generator so 24 hour electricity. Located in a quiet, upscale neighborhood.
It isn't a hotel per se. It is a condo complex. But some of the units are available for rent.
