I had a lovely time at Kelly's and Ruaidhri's place. They both were very kind and welcoming and gave me a lot of tips on what to do in and around Galway.
If you consider coming here, you should know they have kids. Even though they were quite considerate and polite, this is something to be aware of.
The walk to the Spanish quarter took me about 20min.
All things considered I really enjoyed it and can only recommend staying here.
