The place is huge and definitely fits 5 people comfortably. The location is very close to the station and many convenience stores and restaurants located a couple of minutes by foot. The garden area with astroturf was also nice to take photos in. Definitely typhoon and earthquake proof as we stayed during Typhoon Hagibis.
The only thing con was we could not figure out the hot water. Instructions were given, however I don’t think they applied to this place. An updated guide with more photos specific to this apartment would be beneficial. Also one of the people in my group experienced a rash or bed bug like bites on the first night in one of the beds.
All in all a private “penthouse” like place, elevator access, with 5 double beds, huge lounge room and couch, TV with netflix and youtube conectivity, two toilets and two showers (only 1 was functioning during our stay, which we were reimbursed), this place is perfect for a big group of people in Tokyo.
