We, two adults and a baby, stayed at Casa Blu in Calabernardo for a week in October. Luisa was a very careful and attentive host who responded promptly to every our request, be it a baby cot, linen for it or an electric kettle (through What's App, we did not meet in person). The place is well equipped and clean.Mind, that it's not a "house", but a section in a holiday apartment block, three rooms stacked upon each other with seating space in the back and in the front yard - and the rooms look somewhat smaller than in the pictures. The beach which is 80 m from the house is rather rocky, getting to a sand beach takes about 15-20 minutes. I think this place is just about perfect for 3-4 persons, for families with children who can make use of the garden playground and barbecue spot just outside the door (shared with the other guests of the block). Another important thing - there is a restaurant nearby, open for pizza or coffee all day, not just dinner in the evening.
