They say they have air conditioning but they don't put it on even if it's 40 degrees outside as an excuse for Covid19 spread prevention as the owner said to me. Anti Covid filters are mandatory in Spain so either the owner is doing something illegal or it was just an excuse for not spending money on electricity.
Nothing healthy for breakfast such as fruit for instance, no gluten free options either.
I don't recommend this place at all, I couldn't rest with the extreme heat and it ruined my stay in Bilbao. Having a good rest it's very important for later have the energy to visit and explore the city and I was way too tired.
