This place is fantastic. It's tucked a good ten or so minute walk from any tourist area so it's nice and quiet. It's very cozy and relaxing. It comes fully stocked with kitchen items. Plates, pans ect... if you plan to stay longer. It's got two conbeni and one grocery store with in two minute walk as well. The only negative is that it's a 20 or so minute walk to the beach and closest station.
My family came to visit from US and I wanted to show them the area around Kamakura and Zushi. T-Reef was an OUTSTANDING host and communicated VERY well. House it located in a perfect area. 10 minute walk to the beach, right next to grocery store, a CREATE, 7.11, and a family mart. He includes all you need to cook. Katase Higashihama beach is an easy walk and best for family's with parking right next to it. For surfing go 2km east and your good to go. House is cozy, clean, and worked well for a family of four. Can't recommend enough.
Blue Lagoon rooms were spotless, plenty of room for 4 travelers, centrally located to beach and temples (we had car) and it had a dedicated parking space.
Tadao, host, was very responsive with any questions that we had. Great communication.
Overall, we really enjoyed our stay and would highly recommend it to others.
