Yokosuka Research Park

Stayed for 15 days and had a very good overall experience. The hotel is located in Kawasaki, about 45 minutes by train from central Tokyo, which may not be ideal if you want to be close to major attractions. However, it’s very convenient for Haneda Airport. The area is lively, with many bars nearby along Nakamise Street. At night, there are people inviting customers into bars, which might feel uncomfortable for some. We added the breakfast service, but the limited 5–6 options stayed the same throughout our stay and became repetitive, so we ended up eating at konbini from around day 10 onward. There is a free small kitchen/common area on the 10th floor with a coffee machine, water dispensers, various teas, a microwave, and a toaster. It’s quite small and can get crowded. There’s also a terrace, but we couldn’t enjoy it since we stayed in winter. Overall rating: 5/5. Great choice if you prioritize airport access over being in central Tokyo.

Hotel was fantastic.

If you're a nerd and think you'd spend the majority of your time in Akihabara anyways, this is the nicest hotel there. It was super convenient being able to stop back at my room multiple times a day while shopping, winning prizes at crane games, or just wanting to use a private bathroom in between everything. The train station was less than ten minutes away. The breakfast was good, especially the coffee and tea, but it was not a buffet. If I could do it over again, I'd save money getting breakfast at McDonalds every morning.
