I stayed here for two weeks, and I'd love to return for the following reasons:
1. The rooms are decently sized, clean, and have helpful amenities like coffee maker/small fridge/safe, air-purifier, hangers, shoe horn, slippers, and all the toiletries that one needs.
2. The firm mattress was excellent for my sleep - they use comfortable Simmons mattresses that feels very supportive.
3. The large window lets in lots of natural light, and the room was very soundproof. Never heard my neighbors or the trains running on the track a few hundred meters north.
4. The breakfast has an amazing spread. They have traditional Japanese, as well as western choices. Many kinds of beverages were also available.
5. The Tachikawa station is a short 8 min walk away, so very accessible. And if you want more food choices, you can cross the street to find many different shops and eateries.
6. The staff at this hotel (including housekeeping) were efficient, courteous, and friendly. On my last day, I had a chat with the chef during breakfast, and he cared genuinely about the quality of food he was serving.
Thank you Nikko Tachikawa.
