My family visited me in Valencia and we really loved this apartment! Definitely enough space for 4 people. So clean and lovely decorated that it just felt like home. Communication was great: although we had some difficulties at the airport and have been 2 hours late, Paula and Diego were directly at the apartment when we arrived. I talked in spanisch with them but Paula could also speak English to include my family as well.
They have prepared a document with recommendations what to do/see/eat in Valencia and were really friendly and helpful.
The apartment is really close to the district Russafa where you can mainly find bars and restaurants - really nice there!
But you have to keep in mind that the apartment is still a bit far from the city center - by bus it took us approximately 30-40 min. but for us it was definitely worth it! I can highly recommend this AirBnB. Thanks you both for making our stay so comfortable :)
