We quite enjoyed our stay in the area. The place was clean and comfortable and we loved the location. There is a bit of street noise at night, but nothing too bad. Probably because we were located right near Eyre Square and it was a weekend. Light sleepers might bring ear plugs, but we are used to central Dublin apartment life, so not too much bother for us.
We suggested a few small/minor improvements to the host to help make future guests' stay nicer (replace burned out bulbs, replace broken iron, fix stuck windows and interior door latches), but these things didn't negatively impact our stay that much. Worth noting only because this is a rental space.
Communication could have been a bit better. The host was a bit rushed and he intentionally left us before showing us where to park (stated he had a work call). However he didn't call us back after to help us out. Instead we had to get in touch with him. That said, he was very accommodating with our delayed arrival at 6:45pm due to traffic and baby issues. So it all evened out.
In the end, the pros outweighed the cons and we enjoyed our time in Galway. Thats why we gave our stay 4 out of 5 stars.
