Edu's place is a really nice, quirky apartment absolutely beaming with character. We never met Edu in person but he maintained constant contact and his friend Cris dealt with our arrival. Edu was extremely helpful with recommendations, directions and general getting around Valencia.
The neighbourhood itself is a fairly residential location about 15 minutes walk to the old town. There are little cafes, bakeries, bars and restaurants around the square immediately in the vicinity of the apartment, but for more activity head into the centre.
Transport routes are close by within 5 minute walk.
Edu's description of his apartment is very accurate.
Overall a great place to stay (we stayed as a party of 4) and we'd definitely return without hesitation.
