What a find! I stayed in the cottage over the course of 3 days. When you are unfamiliar with the area, I reccommend that you drive in the day time as the condominium is a little difficult to find, but when you arrive in the general area the parking is clearly marked several times. There was no front desk but the owners had emailed us a very detailed welcome letter that included check in information. Actually, the only time I interacted with anyone was the owner in the last day when I left and he passed by and asked how our stay was.
Upon arrival, we entered and on the table were detailed maps in japanese and english with important landmarks in the area. Additionally, I was pleasantly surprised to find coupons to some local eateries.
Eveything about the cottage was very cozy. The interior was smaller than I imagined from the pictures, but they had eveything from a full sized fridge, has stove, cooking appliances, a big tv, complimentary wine, and even a 60's record player. The toilet and bathtub were 'outside', and since it was January it was pretty cold.
There are some beaches in the area, but it was too cold that time of year. Instead we drove to some nearby attractions plus the cherry blossom season had begun.
I highly recommend this place.
