Ignacio is a very friendly person and made sure we (my friend and I) had everything we needed. Check-In and Check-Out were very easy.
The apartment is very modern and has everything you might need, it comes even with a little bit of coffee, tea, salt, etc. It has working air-conditioning, the windows overlook the streets and since the apartment is located in the corner of the house it feels quite nice.
Although it's a great studio apartment (with couch, sofa, two additional chairs) it might feel a little small for two persons. The bathroom is very small (but comes with everything!) and is right next to the bed, but the door doesn't really close. It's all fine, it just might feel very tight. But this might feel different for everybody.
The apartment is located in what appears to be somewhat like "China town" of Valencia (if that even exists), because there are a lot of Asian restaurants cloe by, but just a few streets further you have a lot of cafes and bakeries for breakfast. The North train station and the plaza de ayuntamiento are very close by and easy to reach by foot.
So, all in all we had a great stay!
