Hampton by Hilton vs Premiere Inn Waterloo

I have booked 2 twin rooms for 7nites for  the first week of Oct at Hampton by Hilton on Waterloo Rd. London and will save approx. $500.00 on these two rooms comparing price with Premier Inn Waterloo (breakfast included at both hotels). The distance to Waterloo station from  either hotel is 5 mins or less.  The facilities at the Hilton hotel appear online to be much better. Stayed at the Premiere Inn hotel last year for 6nites without breakfast included and paid much more than my reservations for this fall.  Thought anyone staying in London would like this info.  Purvis
