I travelled with my family. We had very nice stay at Valencia! The apartment location is near to the city center. You can walk or use the metro for 2 stops. The Bioparc is at one stop of the metro.
The apartment was very clean and perfect for three of us.
Ilya is very helpful. He met us earlier than the check in time and we left our luggage at the apartment and came back later when the apartment got ready. Also Ilya gave us some useful information for near stores and sightseeing in Valencia. We highly recommend this apartment and the host.
