The two recent positive posts from genuine students from Ireland seem to contrast almost totally with the negative stories from London. They're so different someone must be lying.
Unless it's changed, OBA always quoted fixed prices and were paid in pounds or euros so no-one need be concerned about the $ exchange rate or the hidden surcharges which make their competitors a lot more expensive.
Accommodation was quiet/spacious/convenient/acceptable for training purposes (and probably better than most students' homes !). If you are shy, you could pay a small supp. for en-suite double as single occupancy. Get real -you aren't on honeymoon or holiday and, also, what do you reasonably expect to be included in a course price which is excellent value?
The notion that you can get just as good a deal in UK is rubbish, if you compare the cost of all that OBA include but which are usually hidden extras in the UK i.e. not included in the course price estimates.
