We booked Mark’s place literally one week before arriving as our other reservation was cancelled without notice. Mark was very responsive and helpful. The house was perfect for our family’s needs. It felt very spacious for our party of 6 (especially by Tokyo standards), was in a great location close to many train lines, and was very clean. The dining area and kitchen were convenient for meals in when we were still jetlagged (a 24 hour grocery store is a 5 minute walk away). Once we wandered out there was no shortage of restaurants nearby, only a shortage of time to try them all.
