This was my second stay at Toyoko Inn Narita Airport Main Building. Because there were many guests checking in that day, the hotel upgraded our room from a standard double room to a triple room, which was very spacious… However, I felt the breakfast selection was much smaller than during my first stay, which was a pity. Next time, if I have an early morning or late evening flight arriving in Narita, I would still like to stay here again.
