Nice and clean room, good amenities (mini fridge, microwave, toaster, kettle). We had a few concerns about repairs that were needed but these have been discussed privately.
One thing to mention is safety - the code to our room could be easily guessed and no option to lock the door manually from the inside, however there is a unique and complex code to use on the front door that meant it would hopefully only be staff and guests from other rooms in the building anyway. This has been raised with the owners so hopefully won't be an issue for future stays :)
Overall it felt that we paid a little too much for what we got, but this is likely to be due to us staying in London over the jubilee weekend, and hopefully the price will reflect the actual experience when it is not such a peak time.
Overall the stay covered what we needed - a bed for a few nights whilst we attended a couple of events, but would begrudge paying what we did if that is the same price all the time.
