Rafa's apartment was perfect! Modern, stylish and perfect for what you need with a beautiful rooftop terrace to sit out on! We arrived and we're made to feel very welcome immediately by Rafa, even tho there was a slight language barrier (my Spanish was not up to par 😂) he explained everything very clearly and left is maps out on the dining table showing us where to rent bikes etc.
The location of the apartment couldn't be better, I genuinely mean that! 5 min walk to the Central Market, you must go! Fresh meat, fruit, fish, nuts, pastries, cheese and many more beautiful foods! Then there is a supermarket a 4 min walk from the apartment (carrefour) which sells everything you need!
As for nightlife, there are so many lovely little pubs and clubs around the town and all very central to the apartment! You will not be stuck for things to do!
While in Valencia, I highly recommend that you visit the Bioparc and the Oceanographic Centre (sea world)
We never took any public transport or taxis while here. We walked to the Bioparc through the "The Turia Gardens" which is a huge park that runs though the centre of the city. It's is incredible! And we cycled to the Oceanographic Centre a few days later. You can hire bikes near by the apartment and cycle to both if you wish, but we enjoyed the walk!
For getting from the airport to the apartment you get the 150service (yellow bus) from outside the airport and get it to a stop not long after you pass the central market (i google mapped this to keep a rough idea of where we were, where we would get off etc and then walked from there to the apartment which took about 8-9mins. We also got the same bus back to the airport. Hope this review was helpful!
