Fran's place is very pleasant and convenient. It's right in the center of Valencia and an easy walk to many places. The public transportation is close by and there are many buses and a metro that go all over the city. The apartment is literally across a tiny street from the Mercadona which made shopping and cooking quite easy. It's also in the middle of Chinatown which is great for people like us who love Chinese food.
The apartment itself is comfortable and clean. The back bedroom (the main one) is very quiet, with a comfortable bed, and has a lovely terrace opening out from it. The rest of the apartment, though small, is quite functional.. There is excellent storage for clothes, and it was great to have two bathrooms. We stayed there for 5 weeks, and found the space to be fine, especially when it was warm enough to use the terrace.
Fran was an excellent host. He was very responsive to requests and quickly fixed a few minor problems. He was very communicative and easy to reach.
The only negatives were that the kitchen was under-equipped which only mattered because I cooked most of our meals. More dishes, pans and utensils would be welcome. But for people who are only cooking breakfast or lunch, it's fine. The apartment also lacked homey touches. It felt like an airbnb furnished by Ikea. A little more art work, another rug, and more dishes and utensils would lift it into another level. That said, we would certainly consider staying again if we return to Valencia.
