We had a great stay at Arturo and Maria's. The room is indeed 'gigantic', and with a hammock! The breakfasts were also awesome (fry jacks were a firm favourite).
The location is good, you're not slap bang I'm the middle of San Ignacio but you are just a 5 minute walk across the bridge. We felt safe even in the dark.
But the best thing about the stay was our hosts. We didn't get to talk to Maria that much but Arturo did everything to make our stay great.
He went out of his way to give us lifts, fed us very well, kept us topped up with water and even helped to fix some broken shoes.
Arturo is also a fascinating person to talk to, and has a lot of local knowledge. Definitely made our stay in San Ignacio an enlightening experience!
