Oscar was a very (I mean very) good host. He was on time to welcome us even though we arrived a little ealier than anticipated, took time to explain everything that is good to see in the city and even including tips on the restaurants and the places to have tapas (we tested most of them and they were great! special thanks for recommending La Brunilda, it was divine as you described ;-))
The location is authentic and close to the city centre on foot. Highly recommended place!
