We were overall very happy with the accommodation at Badesi and the description is highly accurate. Once in Badesi, it is very easy to find with the instructions provided, although getting to Badesi is another story if you are not familiar with Italian roads and drivers! Avoid Sassari if at all possible when driving from Alghero as it is a maze with minimal sign posting!
The accommodation is basic but comfortable and is ideal as long as your not wanting to cook extensive meals. The area is very safe and the communal pool area is excellent and quiet; a great place to relax.
Music can be heard from a local bar every evening but this was always over before midnight so it didn't bother us at all. We struggled somewhat to find good local restaurants although this was probably more down to bad luck. However, K18, a restaurant on the road to Badesi beach is excellent and the owner speaks a little English. The nearby beach is very nice - white sand and very clean. The beaches and scenery in Sardinia are far superior generally to anything Spain or Greece has to offer.
In conclusion, if you are looking for a great value for money place to relax and unwind, you cannot go far wrong with this apartment. If you are thinking of travelling to Sardinia, I would recommend doing so sooner rather than later as the tourism generated from the budget airlines is going to make dramatic changes to the scenery over the next few years.
