San Jordi (Sant Jordi de ses Salinas) is a village / small town located very close to Playa den Bossa and 2 of the best beaches on the island: Ses Salinas & Es Cavallet and with easy access to get to Ibiza Town. The village itself isn't one of the prettiest of villages in Ibiza but if it's all about location then this is a great place to stay.
If you are coming to party in Playa den Bossa & Ibiza Town (but of course not party in the villa, please!) then this is ideal. It's a villa that it is easy to get taxis from, you can walk to the supermarket and you have good restaurants nearby if you aren't planning to hire a car
If you are coming to relax then you won't even know the party side of Ibiza is close by. Head to the amazing beaches at Ses Salinas & Es Cavallet, enjoy time at one of the many beach clubs such as Jockey Club, or a more relaxed atmosphere at Beso Beach Ibiza. In the evening enjoy dinner in the village, or head to Ibiza Town for a walk past all the millionaire yachts in the marina and find a great restaurant to enjoy dinner.
And if you are a family with teenage children this could be the perfect location - quiet enough for some family members, but close enough to the nightlife for others.
