Mimiko is a great host, she really made everything super easy. The apartment itself is very good value, it has everything you need including very fast wifi internet. It has two good sized rooms and a good sized kitchen, living room and bathroom. Everything was working fine. Perfect for a business trip.
The location is not in central Valencia, and be prepared to do a bit of walking or catch the train if you want to see the highlights of Valencia. Although for me it was perfect as I was there for business.
