This apartment was an excellent place to stay in Gallway for a week if you have a car. It was a great value and it worked well for us. The unit had everything we needed and was well maintained by the owners. The communication with the hosts was prompt and clear. The space was pretty clean and well decorated.
Now that we have stayed a few more places in Ireland I would say the tap water at this place was particularly bad to drink, it was very hard and gave me a sore throat which went away once we switched to only drinking bottled water. We haven't had this issue drinking the tap water anywhere else.
If you are sharing the unit with a guest in the living room I would just warn you that the water pump is very loud when flushing the toilet or washing your hands. This just means that using the bathroom at night can disturb sleep.
Overall, I would recommend this place!
