We stayed at Ken's place for about 8 days. We had a great experience of Japan! The flat is a couple of blocks from the Sasazuka Metro Station, with all the conveniences we needed very near by (markets, drugstores, bakeries, etc). It is only one station away from Shinjuku Sta., but in a very quiet residencial neighborhood. We were in a group of four people (family) and we had no trouble with the space: two very comfortable beds, clean bathroom, heating, everything. All the instructions are very detailed and clear, Ken is very kind, answers all messages promptly and was very helpful with our specific needs.
