Carlos was an amazing host and has a wonderfull apartment is the centre of Porto! He kindly received us, showed us around the aparment and gave us the inside tips of Porto which really came in handy. The aparment is well located, just one street from the shopping district. Everything in Porto is in walking distance of the aparment which is also closely located to the metro (goes straight to the airport). Carlos and Helena's place is well equipped (coffee machine, oven, etc), very clean (read brandnew) and is provided with soft towels. Carlos even left us a bottle of wine!! This is all we could have wished for!
