Raul is an excellent host with many great suggestions of what to do. His flat is very well situated to all the important sites of Porto, especially the Museum Soares being right next door which helps guide you back to the location. Also, his place has all the amenities that you might need -- and more. He thoughtfully provided water, oil, etc and also a bottle of wine on my welcoming day, as I do not drink beer. Only the noise can occasionally bother one but I became used to it by closing the balcony doors when I needed to rest. He is a great host and his place is wonderful!
