We arrived at the apartment on Friday at around 1:30 and it was still being cleaned, so we popped out to the carrefour express (which is less than a minute away!) to pick up a few things until the apartment was ready. German met us and was very friendly and explained how all the keys worked and what was in the apartment, worth mentioning he had cleaned it amazingly, it was practically sparkling.
As for the apartment, it has everything you could need for a short break in the wonderful city of Valencia, a small cooking space, a nice sized fridge and a sink, the bathroom is lovely, with an overhead walk in shower and feels spacious. The bedroom is a great size, enough room to store your bags and hang up a few items of clothing, the bed is unbelievably comfortable, we had a great few nights sleep which is really important when you're spending the whole day exploring.
Location wise, you couldn't ask for better, the park is about 2 minutes walk to the right out the apartment door, and the cathedral and large open square about five the other way. Also worth noting there is a bike hire shop next door! It's called PassionBikes, and we found it was much cheaper than some online hire places, it cost us 36€ for two whole days for two bikes and we took them all the way down to the beach which I would recommend as a great day out.
So in summary you couldn't really ask for a better place to stay, super clean, has all the utensils you need, a lovely host and a perfect location. Don't look elsewhere, book this apartment now! I promise you won't regret it.
