Sinead's lovely flat was a perfect base for our stay in Dublin: we rented it as a couple but it's spacious enough to accomodate four people as it has a spare bedroom as well.
The decor was what made us choose it and I was amazed to find out that it was even more stylish in person: often photos can distort a bit the truth but in this case they represent well what you'll find. Also, we had excellent communication with Sinead: very clever self check in and clear instructions.
I'd definitely recommend it to friends for future stays in the city.
