We stayed at Hilltop Hotel for one night only prior to flying out of Tokyo. If you google Hilltop you can read a little of its history but despite its age, everything was well-maintained and the exceptional service was of a level rarely seen in hotels nowadays.
The staff were extremely accommodating, allowing us to check in earlier so we could enjoy one of our last days in Tokyo and delivering our luggage to our room in our absence. They also stored it for the day after we checked out which meant we could enjoy the day out without worrying about bag storage!
Upon arrival we were shown to our room by a really lovely man (unfortunately we didn't catch his name but his service was exemplary) and asked if we would like to enjoy some traditional Japanese tea in our room. The tea was delivered shortly after with some Hilltop cakes which I think you can also purchase as a souvenir.
Our room was tastefully decorated in an older style but everything was clean and the room had been modernised.
Location wise, the hotel is situated close to the university, "Booktown" and an area filled with music shops. We also noted many shops specialising in snow and ski wear. Although the area is fairly quiet it is quite centrally located and we found many cheap restaurants for eating and drinking about 10-15 minutes walk away near Kanda station (the area is called “guard-shita and is under and around the station). After dinner I had a long bath in our room and relaxed in our Hilltop yukatas. I wish I had asked if we could buy one of these as they were really comfy!

We chose the bed and breakfast option which meant we got the choice of a western or Japanese style breakfast in the morning served in a beautiful dining room.
My only regrets of our stay were that we didn't get to try to Bar Non Non (which only seats 9 guests) as I was unwell with a head cold and that we only had one night.
The bed was a little hard but the most comfortable of our trip to Japan.
Overall, a really pleasing stay - thanks to the staff of Hilltop.

We stayed in this hotel for 2 nights at the beginning of our trip. The location was fairly decent, not too far walk from the nearest train station (Ochanomizu) although as the name suggests it is at the top of a very steep hill so taking heavy cases was a challenge! The staff here were very helpful and lovely (as most of the people are in Japan). We stayed in a Japanese style room with tatami mats but a bed rather than futons. The room looked like a film set, really beautiful with an old writing desk. I did find the room to have an odd smell to it (there was an ashtray provided on the table) so I think it may have been stale smoke. I did get used to it eventually. As soon as we arrived we were served green tea and biscuits to the room which was a nice touch. The bathroom was dated and while not unclean it was a little aged. We didn't find there was much in the way of restaurants or nightlife around the hotel, so generally always took the train somewhere else. Nice stay for the 2 nights we were there, was lovely to stay in such an old building. Not sure I would stay again but that's down to the location and not the hotel itself.

On our first evening in Tokyo at the Hilltop Hotel, we asked the desk clerk for a sushi restaurant recommendation. He gave us one, and then realized we would have trouble finding it. (It was downstairs in a mall.) So he guided us to it on foot (about 10 minutes), told the sushi chef about our preferences and desired cost, and went back to the hotel. We were astounded. Plus, it was a very good meal. Hilltop Hotel is an older building, but has been modernized. The room was comfortable, the lobby was comfortable and welcoming, and I had a very fine traditional Japanese breakfast in the hotel restaurant. It's not as imposing as it looks in the official photograph (I had expected it to loom over the neighborhood - it doesn't), but it's next to a large university and the neighborhood is lively. We (a couple in our 70s traveling for pleasure) highly recommend it.
