The Madeleine Inn was fabulous by and large, but I did have a couple of issues with my stay there:
The air conditioning was the most notable. We arrived late on the first day, and turned on the somewhat tiny window-mounted AC unit around 9pm. It didn't really cut it. I had kicked off every blanket and as much as clothing as possible, and was still lying in bed sweating until about 4:00am, fantasizing about central air and debating sleeping on the porch outside. Having learnt my lesson, I left it on full blast 24/7 the remainder of my stay (and even then it never really got cold), and didn't have another bad night of sleep. The last day of my stay I overheard other guests complaining about their AC at breakfast, and the inn keepers mentioned something about cleaning filters. I sort of feel like the AC units needed to be twice the size to really cover the size of the somewhat large rooms - but who knows, maybe it was the filters..
The only other gripe was that our room's bathroom had no sink - it was in the bedroom proper, and so getting up late at night to use the bathroom meant waking up my gf (or her waking me up). Most of the rooms were like this too. Or particular room (morning glory) also had a warning that if the adjoining room was using the shower at the same time, we might get flashes of cold water. We never had an issue with that, though.
Everything else, pretty much incredible! Breakfast was beyond delicious, the location convenient but cozy, the staff super nice, and the ambiance just crazy cozy. I'd stay here again if ever we go back to Santa Fe - especially in cooler weather!
