Close to the port - only about 4-5 mins of walking to get from ferry. The office we used for hiking the volcano (Magma Trek) is about 10 mins walk. Plenty of places to eat a good lunch before the sunset hike along that walk, and a pretty good grocery. Sigrid offers to prepare breakfast, but we did not take advantage of that so can't review.
Everything was in working order. Nice large shower for removing volcanic dust! Be sure to dump out your boots before leaving the hiking trail, as there is not a yard area close to the apartment (street in front). During the day there is noise from the scooters and 3-wheeled trucks in the street (kitchen is open to the air, but with a wall in between street), but was quiet at night.
