We are Long Beach locals and stayed 2 nights while our house was being fumigated.
Check-in and lockbox were easy. Harry provided very detailed instructions/information for our stay, including details about how to use the shower and window shades. Plenty of amenities, including K-cups, snacks, drinks in fridge, extra towels, dish soap/sponge, detergents, and shower products. We were trying to get through our work week while staying, so all the little extras made things way easier for us. Location is prime ... a SUPER great spot in Naples, literally steps away from the bay/canal, and so close to so many Long Beach sights/locations/activities.
The only challenging parts were adjusting the shower water temperature (Harry provides instructions, but it really can be finicky) and poor water flow in the kitchen faucet (there were water deposits in the faucet head, which made it hard to rinse dishes).
Also found the mattress in the front bedroom too depressed in the middle for me --- my back and neck were sore in the morning after sleeping on it -- but I like a firm bed, so that's probably a matter of personal tastes.
