We are two middle aged couples visiting Tokyo for the first time on our way back from a round the world trip and looking for either an hotel or an apartment/hotel for 3 nights. We've looked at the Shinagawa Prince which looks about right but we want to find something a bit cheaper, if poss. Can anyone recommend a hotel with reasonable sized rooms plus shower; we don't need anything special as we're not planning to spend more than our sleeping time in our rooms but we want it to be central for dining, transport etc. Are there any hidden gems out there for British tourists on a budget? Any suggestions would be gratefully received.
