I travel all the time and I've seen a LOT of hotels! The Capitol Hotel Tokyu is the nicest hotel that I've ever visited.
The Sanno Suite
This is an absolutely huge hotel room in a city where space is at a premium.
The Great Room
This spacious room has a great open feeling and best of all, a view of some beautiful green trees - very rare in the city.
It's very well appointed, with a shower chamber that's so big you don't even immediately know you're in a shower.
This room itself would be a very nice and complete guest room in most other hotels, with a king bed surrounded by a desk, drawers, and a sofa.
