Don't hesitate to pick Mark and Hope's place. They're one of the nicest and best hosts I've experienced, but even if you're not looking for too much interaction, you completely have your own space. The bed is incredibly comfortable, the location is beautiful and a perfect getaway.
Their place is beautiful, spacious, full of nice touches (they left sparkling water and some nice treats for us in the fridge.) You can tell that they really wanted us to have a nice stay. We barely had a chance to interact with them because we woke up very late but we were very appreciative of everything they provided for our convenience and their flexibility.
The location is about 20-30 minutes from Santa Cruz, but close to other beaches and small beach towns nearby and perfect for whatever you want to do. It's also very close to a lot of hikes that seem like they would be amazing. There's a nice garden area you can hang out in. If you're coming from the city, as we were, it's totally worth it to book a stay here. The weather is amazing in the summer, we woke up to perfect sunshine and temperature.
Highly recommend the place, it has the cleanliness, and amenities of a hotel, with additional space, personalized touches, friendly generous hosts, flexibility, etc. Really the best that Airbnb has to offer.
