I stayed in a really cheap one in Okinawa, and it’s just like as you described. Noisy, claustrophobic, people would come in and out at all hours of the night and you could hear people snoring. So that really put me off staying there again. But having been to this one yesterday it’s completely opposite of my initial experience. I’ll stay at this one next time I’m in Tokyo.
This time I didn’t stay there as I was just there to do photos for them, but it would’ve been a 3rd of the price of the hotel I did stay in and a lot cooler.
