We stayed 3 nights in this apartment and enjoyed it.
The apartment is new and nicely decorated. The bed is big and comfortable, and the kitchen is good as well.
What we liked the most about the apartment is the location; it is perfectly located, near many restaurants, bars, cafes, grocery store, tourist attractions etc. You can walk anywhere from there.
The apartment is noisy as the window is not very soundproof, but I think it is the price to pay to be located so close to the center (we found that it was usually the case throughout Spain). Make sure to bring earplugs.
The only little downside is that the apartment is one of many rentals so it felt like some little basic things were missing (for example laundry detergent) and sometimes we would have appreciated a little more help from the owner, but he still answered quickly when we messaged him and gave us a map and some tourist info/recommandations.
