We are a group of 3 adults and 2 kids (8 yo) staying in the apartment. We occupied the entire apartment with 5 rooms available! It was great staying in this apartment! Clean and location is good.. Cooking was not an issue and utensils are available, even cooking oil (Not sure if it's left by previous guest). Mr Fumihiko was helpful and was at the apartment the last day to send us off. He even offered us 2 umbrellas to continue our trip to Hakone as it was raining and forecasted to rain for the next 2 days..
I would recommend this apartment for big groups but not for elderly as there are narrow steps and 3 floors to climb as there is no rooms in the ground floor.
Over experience was great! Thanks Mr Fumihiko for his great hospitality!
