Yotel was a fantastic place to relax during a long layover between long overseas flights. For my short stay the tiny standard room was just fine. In fact the room turned out to be the perfect quiet oasis that made my >24 hour trip infinitely more bearable. The shower (and amazing organic shower gel) were unexpectedly outstanding! I was worried about traveling to Terminal 4 from Terminal 5 and back again, but it was extremely easy and relatively quick (even as I needed to go out through immigration and back in through security) via the free buses.
