João was professional, warm and informative host. He gave us all the necessary information upfront and was available for questions. The flat is in the quieter, cool neighborhood of Alfama which has a ton of small bars and restaurants. Also the best Fado music! It's about a 15 minute walk to the Bairro Alto area so be prepared for that. Also don't stay here if you're allergic to cats - the apt underneath has cats!
