Location Location, all was in 10 minutes distance. But besides that, Isabel was a great host to welcome us with city tips. The nice, shady rooftop terrase was great for a last drink in the evening, or to relax inbetween sightseeing - even with a shower outside, or just to watch people at Calle Sierpes. the Patissery/ bar on the street had great good-night drinks :-), and never miss the fantasitc Churros at the Setas. Thank you Isabel, we will come back.
for fellow visitors: One more thing: you can take a cab for 25€ from airpot to Placa del Duque/Calle Campana, that's the easiest. And for the Alcazar, reserve a ticket, the line takes 2hours!
