It's a very quaint and nice little airbnb in a really spectacular part of the country. If you're looking for somewhere quiet, this is the place.
There is internet, but if you need something responsive it isn't the best for that. I'm not sure if it's upgradeable, but a new router might help it. There's also no phone signal inside, and barely one outside so calls/4g are difficult. So it really is an internet detox.
Unfortunately we had to leave early, but we had a lovely time in Sligo and would definitely recommend staying here. It was brilliant value for money.
