Rebeca offers you a small, but lovely apartment to stay in when you're in Porto. It is very cosy and perfect for 2-3 persons. You find everything you need there (towels, hair dryer, soap, dishes, even some things to cook like oil and spices) and the communication with her is excellent. To the central station, you walk about 5-7 minutes, to the city centre between 12-20 minutes. So, you can walk nearly everything!! But, if you more on the lazy part, the metro station is just one minute away! :-)
Also, Porto is a very relaxed city. Go to local restaurants and cafés and try their amazing (but also heavy) food (attention: reservation is a must in some small, 'family' restaurants!)
Two tips from us:
If you there and it's still warm, go to the bar 'BASE'. It's perfect to watch the sunset and have a drink while chatting and listening to chilled music.
To do a port wine tasting, you can go to almost every wine cellar. We went to 'Augosto's' which is a small (in comparison to the others) family business, you will love it!
We will definitely come back one day!
