Our experience (5 adults and a 2 year old) of Rafa and his wonderful apartment is an example par excellence of what a 5 star stay at an AirBnB should be. From his communication and welcome, to first impressions of the apartment and total stay, all was absolutely topnotch. Appliances were top of the range (bosch), artwork was excellent, and he left us welcome extras (snacks, fresh oranges, bread/milk/cereal for breakfast, bottle of wine) and a thoughtful toy for our two year old. Not only that, he took 10-15 mins to share some of his favourite things to do and places to see in Valencia, leaving us a hand written note/guide by his wife. A highlight of our stay was a rooftop bbq which was amazing - all bbq amenities were provided (minus food of course!)
This is was a fantastic experiences and comes highly recommended. The neighbourhood I think would normally be quiet, but it was fallas - nothing is quiet during fallas. One thing worth mentioning is that if you have young children, they need to be watched closely with the metal spiral staircase but we managed this well and will happily stay there again inspire of this. We moved on to a 5 star hotel in Valencia and can honestly say we miss Rafa's apartment.
If it is available, do not hesitate to stay there if you can - you will not be disappointed.
