This is a lovely apt located just a few minutes walk from old town and about 10 mins walk from the park (which is great for runners or bicyclists). It’s possible to walk to the ciudad de las artes from here (25-30 mins walk) and r the oceanographic. You’re also close to major bus lines and the train station (the Nord one). A friend and I worked remotely from the apt a few days, and the Wi-Fi worked well, as did Netflix. And communication with Carmen and her daughter Iris was smooth. The only issues were the washer dryer (the dryer function didn’t work, but Iris was going to look at it) and the recurring smell of eggs/methane in the apartment. It was a smell we noticed in various places in Seville. I don’t think it can be fixed and it’s not a huge bother as it comes and goes. But it’s definitely a reason to keep the balcony door open.
All in all, it’s a lovely, well-kept place and a perfect base for those visiting Valencia. Highly recommended.
