This apartment is by the town of Oropesa del Mar, in the Marina D'Or resort. It is literally only a couple of minutes walk onto the beach itself with a clear Mediterranean sea. There are many, many restaurants and cafes nearby for eating out but there is also a fully stocked supermarket nearby should you wish to do some cooking. There is lots of entertainment for children if they get tired of playing on the beach: gardens, a secure children's play area and a large communal pool. It is an hour's drive or train ride from Valencia to Oropesa del Mar. All the normal watersports such as windsurfing, sailing etc are available at the beach.
All the normal facilities such as banks, pharmacy, clothes shops are also a short walk away by the Marina D'Or spa resort.
If you wish to drive to nearby towns, there are also lots of interesting historical sites such as exploring the underground lake and caverns.
The main attraction is however the Marina D'or Health Spa: Europe's Largest Spa & Health Resort - see details about it below.
