Sola hotel was one of the nicest places I stayed while in japan. The hotel & room itself are beautiful, clean and modern. The ZZ JR line is like 10 minutes away. There are also two actual supermarkets just around the corner.
The true stand out is the people who run Sola. Everyday they went out of their was to help me and my boyfriend (who had sustained an injury while in japan) they were so kind and responsive and always offered a little bread, fruit or onigiri for breakfast. There was also a really nice nespresso machine in the lobby which is so small and cozy. It is a family run business and their kindness was just so overwhelming. I can not recommend Sola hotel enough. Next time I return to Tokyo I will be staying at Sola for sure!
