The flat was very clean and tidy when we arrived. Karin provided many tips and guidebooks for the area. We didn't see her very much, but was very responsive to when the toilet was clogged.
The location is excellent - near O'Connell Street and transportation. That being said, it is on a busy street, so bring ear plugs and a sleep mask if you're a light sleeper. The place is a good size, though it looks a bit bigger in the photos. The bed is in a loft and is low to the ground so be prepared for stairs and bending down. I personally did not find the mattress that comfortable, but my husband thought it was fine.
