We had a wonderful time at Casa Luz in mid-April, 2023. We stayed six nights with our three grown children and one friend (all aged 25-32). The house is beautiful and clean, with room for everyone both outside and inside, and it had great A/C. We made dinner a couple of nights at the house and also had two dinners with Chef César - which were terrific but not necessarily a bargain. We didn't see any monkeys for the first three days and then saw many, especially squirrel monkeys. We also saw a sloth, toucans, macaws and some ground-dwelling rodent-like animals - all from the house decks. We heard many howler monkeys but didn't see them. As others have said, a store just 100 yards or so away + a very cute restaurant (only had breakfast there) next door.
We went on three excursions - Off the Beaten Track, kayaking in an estuary, and ATV'ing - all terrific. Went snorkeling with a company we found online. We spent an afternoon at Playa Esparilla (sp?), with beautiful water and beach. We didn't rent a car but used a van recommended by the concierge Mefi and then a cab which could fit all of us and made arrangements with the driver for other trips. Mefi is super-helpful for whatever you'd like help with - excursions, restaurants, van arrangements for San Jose to the house. Overall, a fantastic, memorable house and trip!
