We stayed at Sai 3/F and it was perfect for our family of 4. Location is as stated, just a few buildings away from Tawaramachi station, which ia 2 stops away from Ueno station. Apartment is modern, bright, spotlessly clean and well equipped with any appliances and amenities you may need. Each sleeping area has its own TV. Itoe-san also responds to queries very quickly. We would recommend this apartment to our friends for sure!
