Marta's place is absolutely fantastic, the pictures do not do it justice .... you MUST stay here. It is very conveniently located, steps from bars and restaurants and a minute from the main square. The space is very clean and well maintained, it also has a nice terrace. Marta is very quick to respond and is very accomodating. She met us at check-in, showed us around her place, made sure we were comfortable and gave us a few tips on things to do in Porto, she also brought us a few local pastries. I highly recommend her place and will definitely stay here again.
