This is a super cute, clean house with a LOVELY front patio, and just a few blocks away from the beach. I stayed here for a month while working remotely full-time, and really loved it. I also had zero wifi issues, though I can't speak to the quality for a larger group (I was here alone).
Just a couple other things to note, in the interest of transparency: the house is on the corner next to a busy street, so you will hear the sounds of cars and traffic. The washer and dryer are SO convenient to have on hand, but they take up space where you'd normally have storage for your clothes -- so if you're staying for a while and are an overpacker like me, you'll just have to use the space creatively (I was able to figure something out, though I had the benefit of having the full place to myself). There were a couple instances where I needed Ryan to refill some amenities (toilet paper, dishwasher detergent), but he was super responsive every time and the items always came the very next day.
Overall, I'd be happy to visit again -- it's an adorable place!
