Overall, we were happy with our stay in Gill and Máirtín's apartment. It's located close enough to the city center that we could walk there with our 2 year old in about 20-30 mins, and we didn't mind the exercise.
The apartment itself is clean and quiet.
We had a problem with the stove one morning and Gill was able to resolve it for us later that day (the circuit breaker had tripped).
If you're tall, you might find the shower a struggle.
