Thats who the deal was through.  I have some mixed feelings about them.  The reviews I've seen are fairly consistent: extremely limited hot water, possibility of being shifted to a less desirable staydublin property, single key (200E charge for a lost key as well), additional 250E security deposit, post trip charges for extra towels, cleaning and "excessive energy use".  If everything goes well, it would be a fantastic value but there appeared to be a lot of chances to go wrong, thus my hesitancy.

I'm still looking.  Amberley House is a possibility as are some of the hotels I mentioned (but would require 2 rooms).  I'll probably wait this out a bit and see if room costs fall any further.

Is the Lower Gardiner area ok?  Seems like there are a lot of guest houses in this area (Lower Gardiner and Talbot Streets just north of the river and east of O'Connell).
