Yolanda's place is a great size for a couple and is well fitted out with cooking equipment, utensils and even nice touches like muesli, milk and a coffee machine. The apartment is close to the old town where all the great food and action is but the apartment itself is soundproof so you can get quality sleep as well.
Yolanda was the best host I have ever had. She was welcoming, friendly, easy to talk to and she went above and beyond to help us like calling around various wineries in Laguarida to help us get a new booking when we messed up and missed our bus so we were to be late and miss the first booking she had kindly made for us. She was also full of helpful suggestions of where to go and where to eat. We were very grateful and I am sure our time in Vitoria-Gasteiz wouldn't have been half as good had we stayed any where else.
