It can get a bit noisy, as the walls are quite thin. And if you have a room towards the street, you might not sleep too long... Also because of the church across the street. But hey, there are better things to do in Sardinia than having a sleep in!
The hotel is located in the main street of Olbia. If you arrive by car, be aware that the street is closed in the evening from 9 pm or so... But there is free parking at the seafront - at the end of the main street (Av. Umberto).
Hotel is clean, room spacious and breakfast is alright. There is a small church just opposite the street which makes sure you don't sleep too long in the morning... Besides of this, good choice to spend a night or two, location is the main plus!
