tontine is around the same price £50

tontine is right in the centre of peebles, so handy if you want to hit the pubs straight away and has a nice wee bar in it.
hydro is a bit more family orientated, not such a great bar, but does have good facilites like swimming pool, snooker etc etc. great breakfast too.
Id stay at both again, and they do single rooms etc.
