We are a party of 3 and stayed one night at the start of our Japan holiday. We caught the NEX to Tokyo station and in stead of getting a taxi to the hotel we were brave and took the Subway. REALLY easy and we saved so much money. The best exit if you have luggage is number 2( because it has an escalator). 1 is closer but lots of stairs. Come out of 1, turn left, then turn into the alley and follow the alley - you are at the hotel! Wish someone had told us that - we got very lost. Lively huge room, nice welcome. We didn't eat breakfast...went back to the station entrance area and found an Excelsior coffee house.
I was impressed with my booking enquiry and the follow through has all lined up. We will return at the end of our trip. Only complaint was noisy air con that I couldn't work out how to turn off but I would ask next time.
