Our family stayed a month in this apartment and enjoyed Valencia and Las Fallas during our stay. Location is good - a few minutes from Turia park and El Carmen city center. Apartment is child friendly, so be free to rent it with small babies - there are no open access stairs, all doors and balcony possible to lock, the floor cover is laminate and it is not cold for babies. Apartment was very clean and equipped with all what we need for long term and even more that was a good surprise for us :)
Be noticed that there is no elevator and public staircase is narrow - so you can't, for example, pull the bike up to keep it at home overnight. But we left our baby cab just on the first floor, so no problem with it. Also there is Valenbisi station with public bikes just opposite the building, so you can explore the city with it very easy and cheap, but be sure that you understood how it works before use Valenbisi ;)
But the main advantage of this apartment it is the host - Gabriella, she is truly superhost! It was a pleasure to communicate with her, all issues were resolved very fast and in comfortable way for us.
So I happy that we used this apartment for our month stay and I can completely recommend it. Enjoy your Valencia trip and Gabriella's hospitality!
