I just realized that hotel in Shinjuku may not have WIFI.
Amenities I need are:
Quiet, clean and comfortable room with good soundproofing of outside noises, A/C, ensuite restroom and shower, English-speaking staff available, WIFI, laundry in hotel or very nearby, easy access to and from airport and major train stations inexpensive places to eat nearby with food choices that are not adventureous for a US tourist.
Maybe Asia Center someone mentioned above may be a better choice? I found one for that looks like it might be around $80 per night at 8-10-32 Akasaka. How is that place?
