Excellent accommodation for us 6 old foggies ! The idea of the cellar is excellent, and we used it well.
Black Grape was well situated for the day trips we had planned in Rioja as well as San Sebastián and Bilbao. The town of Ollauri is tiny but there is a great spot for coffee and snacks in the morning and a grocery store for filling up the fridge at the town house all within 50 metres of the town house. There were only four of us but this rental has plenty of room for more people. Highly recommend.
