Haya's house is located in the Liberties, which is the part of Dublin where a lot of breweries have been and some are still located. It's very close to the Teeling brewery, St. Patrick's Cathedral and Dublin Castle. If you want to take a bus, there are several bus stops nearby.
Our room was very clean and tidy, the bed was comfortable and the bathroom was spacious and clean. The only small flaw was the street in front of the window which you could hear during the day, but at night there was not a lot of traffic, so it was not too big of a deal.
Haya gave us a warm welcome and communication was easy.
Overall I can highly recommend Haya's accomodation and I would stay there again.
