If you're looking for a nice stay in the quiet and more rural-ish parts of Sligo we can recommend Maura's place wholeheartedly.
Maura is a very friendly and helpful host. She's very responsive and always around when you need her, but wouldn't be intrusive in any way when you want to mind your own business.
The apartment is as advertised - well maintained with all the amenities mentioned in the description available for you. There's a number of toys and a board game or two available too, which can be a life-saver when you come with kids and the weather is not as good as you would wish. Also, there are two dogs at the property - they're very friendly and my kids (5 and 7 y.o.) loved them.
One thing you may consider important if you're a tall person: the roof is sloped (is "pitched" the right word?) and ceiling on the 1st floor is quite low - I'd imagine it could be a bit of an annoyance for people who are very tall; I'm 177 cm tall and I still managed to bump my head here and there a good few times; conversely, my wife - 162 cm - pretty much didn't notice the low ceilings at all :-)
The village is rather quiet and a bit remote (you need to drive to places you may consider worth visiting / doing, whether it's a forest trail, a small hike or a beach), but there's a shop around the corner as well as a pub and a rather nice playground in a walking distance, so - at least in my opinion - it's a very nice place for a "base" for your holiday trips and a nice alternative to the popular and busy places. It's also in the delivery area of SuperValu if you don't fancy wasting time on shopping.
In overall we really enjoyed our stay in Ballintogher and we can recommend it to everyone who's looking for a nice and quiet place that's not completely remote.
