We didn't get to meet Gaia but her sister Sarah was waiting for us when we arrived, check in was easy and Sarah spent time explaining everything we would need both inside the apartment and locally, she even offered to take us to the beach over the weekend, but sadly we had plans. It's a 5 minute walk to the colloseum, which is at the end of the road.
The apartment was spotlessly clean and the bed is very comfortable, there is plenty of space to relax after a long day's sightseeing and the shower is great too, had no issues with noise, as per some previous reviews, next time I'm in Rome I'll definitely stay here again.
