We had a wonderful week at Diana and Estaban's apartment.
It's location couldn't be better, literally 300m from the Malvarossa with an abundance of great restaurants to choose from. For those who wish to use public transport, the metro station is literally right outside, and buses are frequent and accessible to the city centre.
We chose to walk a lot (100km in total in the week!), however, the weather was fabulous. Spanish warmth, but a lovely sea breeze. 15-20 minutes walk you are at the main marina, and not too much further than that you reach the Jardines del Turia which have beautiful gardens, nature, and sport in abundance. They provide a great way to walk to the historical part of the city, without having to meet any traffic.
The inside of the apartment is incredibly clean and well maintained. The terrace is a fabulous place to sit out. Diana and Marcelo provided transfers from the airport (a small, but very worthwhile extra cost). Marcelo even picked us up at 4:45am for our flight!
Great hosts, excellent communication and would certainly recommend this apartment for your stay in Valencia.
