We (two families) have been in Ostra Vetere early in the year (April).
The house: tasteful, modern, well functioning equipment, great beds, billiard, table football, a Swedish oven in the evening...everything clean and well maintained...
Outside facilities: breakfast in front of the house and in the afternoon behind the house good BBQ facilities (great flexibility to follow or escape the sun, depending on temperatures), kids (9-13) have enjoyed the swimming pool, very quiet place with fantastic view
Infrastructure: highlights have been for us Grotte di Frasassi, Urbino, beach of Senigallia, also good area for biking, supermarkets and restaurants have been all good.
We have been many times for holiday in Italy. This house is outstanding, and also we enjoyed the region of Marche. We definitely recommend this house and we will be back! Thanks!
