The flat was gorgeous and got everything you need for two people and more (including, for example, a hairdryer, plaster or a bottle screw to open a bottle of portugese red wine ;-)). The location was perfect - the most interesting spots are within a walking distance. And last but not least Henrique is a great host: he gave us a lot of valuable tipps (about where to eat, where to drink, which places to see,...) and even organized the airport transfer for us.
I definitely recommend it!
