I was in Valencia for my language studies and chose Mercedes' apt. Good decision! Very well located, centrally to the historic city, close to metro and with shops close by. Though still quite. The terrace is just awsome. The apt is very nice, modern (think just recently renovated) and got everything you need: kitchen with fridge and freezer, micro; sofa, tv, wifi, washing machine and a portable AC. On top Mercedes has 'member' cards for valenbici which is very helpfull for short trips, a station is just around the corner to pick up a bici (advice: check online or with app whether bicis are available).
Since I had a longer stay here, Mercedes made sure that apt was cleaned and towels etc were change. So, excellent service! Though, you would have to return favor by watering the plants... :-)
Summed up: great location, centrally, all you need!
Will go for the apt again when/if I come back to Valencia!
