Thanks all for your recent responses. After a lot of deliberation we have decided to treat ourselves to one of the above options. Both seem to have good and not so good points after trawling through reviews. The Estherea looks classy and elegant but the noise seems to be an issue and im a very light sleeper- although maybe I wont hear anything after a couple of nights out in Amsterdam!
The Toren is more expensive but has a great special offer on through TA- free upgrade if they have availability, which for 2 nights end of Feb a monday and tues so Im thinking we might have a good chance? Also free drink, chocs and half price breakfast with the offer.
I would really appreciate some advice
