Me and my family were staying at Ramon's place for 4 days. From the very beginning Ramon was very easy to communicate and he was very friendly and supportive for all of the period of our stay. He even bought a baby-bed, baby-chair and holder for a wet clothes to dry for the time we were there!
Appartement was very clean and cozy. It has everything you need for a stay. And if something was needed Ramon was very open for chatting and helped us to solve any issues. He even allowed us to check out much later than it was needed: we had a flight at 22:05, and check out time is 12:00. But he let us stay till 19:00 for our comfort. And even called us a taxi, wich was little difficult in Valencia.
Very important thing is language! Because no one in Valencia speaks English, Spanish only. But Ramon does, and it was just a gift!
Apparent is located just next to the City of Arts and Science, and nice mall calls "El Saler" which has big supermarket. Ramon's kitchen allows you to cook at home, so you may buy a products and cook by your own (which we needed because of baby).
Also it's not far from city center - about 7 minutes by bus.
It's not on a very sea side, but it also can be an apartment for beach rest. We were going beach every day in a morning and afternoon. The one way walk takes about 25-30 minutes (2,4 km).
It was a pleasure to stay at this place. I was worried about space in there for 2 adults and baby, but it was very comfortable and we felt no need. I do recommend this place! Ramon is a very nice person and good host!
