My wife and i stayed at Hotel Fukudaya in August 2010, the hottest August on record in Japan (literally). We were sight-seeing and attending a conference at the University of Tokyo, Komaba Campus.
For access to Shibuya and/or the University of Tokyo, the location is great (not too close and not too far). The Shinsen Station on the Keio Line, which goes to the University, is within easy walking distance, even in the oppressive heat of 2010. In normal temperatures, walking to Shibuya would be feasible. However, dragging luggage up the hill from Shibuya Station would be difficult, and people unfamiliar with the area will be hard-pressed to find their way.
No cab drivers will be able to find the hotel using the address, but many will know it by name. Notably few taxi drivers speak English (or even read Romaji characters), so try to have the name and neighborhood (Aobadai) in Kanji and/or Katakana/Hiragana (consult your guidebook). If you insist on taking a bus with all your luggage, go to the West Bus Terminal and hop the 21, or any bus stopping at Dogenzaka and get off at the second stop.
The staff at the hotel was incredibly welcoming and friendly. At least one staff member speaks English (most do not), but all are willing to work with whatever Japanese you have to offer.
This was our first hotel in Japan and we were somewhat unsure of what to expect. We had read warnings regarding tiny rooms, Japanese-style toilets and baths, etc. Naturally, the rooms in Fukudaya are small, but perhaps larger than others in Tokyo. The rooms (we stayed in two because we unexpectedly extended our stay) were very clean and comfortable. Both were Japanese style with tatami floors. The first room (111) had an ensuite bath, which was clean and not particularly unusual by Western standards. The second room (221) had a lavatory, but shared shower right outside the door. The shared shower was clean and quite large. Notably, the first room (111) shared a wall with the lobby and a wall and window with the street. We never noted any significant noise.
All of our subsequent hotels in Japan are now compared in relation to the high bar set by Fukudaya and none are better.
