We got a rental apartment for the week we're in Sardinia through the dive company we were diving…read morewith (Nautilus). Isabella, the agent, was really friendly and nice, and also very thorough. She took us personally to the apartment (~8 minutes drive from the office) and showed us where everything is.
The apartment however, is just okay. It has a kitchenette with a gas stove top, a mini fridge, and an oven. The outside area has a barbecue (coals, not electric) and is windy and shaded. The toilet is very lacking. It has a bidet but that's about it. Be prepared to buy your own shampoo and even toilet paper (unless you use the bidet). Bedroom has a hard spring mattress and two VERY flat pillows that are practically non-existent. That's it. It's a basic, no frills apartment for 700 Euros. Bit pricey for what you're getting, but you're not going to get anything cheaper (and not by much) unless you use an Airbnb.
