This apartment is in a great location - close to sites, a lovely park, the metro, cafes and restaurants. We stayed here for Las Fallas and it was perfect - we were within walking distance of everything we could possibly want to see/do for Las Fallas.
Check-in and check out were very easy and Jorge has stocked the apartment with information about Valencia and things to do there. The apartment is larger than I expected, especially the bathroom. There are some very nice "extras" in the apartment as well.
If you a planning a trip for Las Fallas, please know that it is Loud until about 3:30 in the morning. That being said, the apartment is located just off the main street in a quiet(er) little space. There are excellent windows that block a lot of the noise. For us, the central location was worth a little noise.
