My girlfriend and I stayed at Dolores' B&B for a single night. She was extremely inviting and accommodating despite our last minute booking request. The place is right on the other side of the bridge from the city center of Galway, so great restaurants and pubs were a short walk away without the night time ruckus we heard while staying in a hostel in town previously.
Her place was quiet, clean, with a very comfortable bed.
Dolores cooked us our first full Irish breakfast and it was absolutely delicious as well as filling :) The coffee was also exceptionally tasty.
Dolores was a very easy going host with a very hospitable warm energy. She was great to chat with about Galway (past and present) and if our travel plans would allow it, would have stayed much longer.
If you are visiting Galway, there isn't another place that would suit your needs better, especially for a couple who is looking for quiet accommodations with your own bathroom.
