The apartment is very well located, near the river and the great Franciscan Well pub and brewery.
There's a bunk bed with a couch below it, which might not be the best solution for longer stays but will work for a short period of time.
Mairead was very nice: communication was good and she helped us with everything we needed.
As for the cleanliness, we found the sheets and towels to be dirty and full of stains and hair. We also found several spiders crawling near the bed, which was not pleasant.
Overall it's a good apartment for a short stay in Cork, but it really needs a cleaning (and new sheets and towels).
