Overall a good stay. We were unfortunately not sent the check in details 3 days prior to check in as stated when the booking was made - this meant we had to chase this up on the day of check in taking up a lot of time on a busy trip.
The location is great for transport and getting around London. The room was clean and tidy although much smaller than expected. Because we were out for most of the time this didn't really impact our stay too much. The air conditioning was a big plus on what was a VERY hot week in London and meant we slept very comfortably.
