I had a great 3 night stay in Villa Rosy in April!
The area is outside of the main part of Viareggio and near a quieter beach called Torre Del Lago, which is just perfect for a quiet getaway! The owners were so friendly (helped out with maps, directions, suggestions) and the place feels more like a B&B, great atmosphere! No problem if you dont speak Italian!
Was able to rent a bike and it is a short bike ride or drive, slightly longer stroll, to a gorgeous sand beach or through the national park (forest like) area to the main part of Viareggio if you feel like a bit more noise. Also very close to a big supermarket.
The room was a good size - note if youre comparing to US or Aus hotels, it is small, but for this price in Europe it doesnt feel too cramped at all, and it was clean. Daily breakfast was good, great coffee. Free wifi was quick and easy as well.
No complaints here, very happy!
