This has so far been the best Airbnb experience we both had. Everything is superb: location, interior design, comfort, welcoming host.
The location is excellent, right in the centre of everything, can't be more central, you just need to walk 200 meters down the main street of Old Town and you are at the most beautiful river-view plaza of the town, or you can use the backdoor to go to the 9th century little secret street that goes up to a beautiful church with a view of the whole town.
Eugenia was a very welcoming host and understanding to our changing plans of arrival. She also gave us a detailed information on the map of everything we should see.
The apartment itself was amazing, everything is done with great attention to detail and coziness: the right temperature, smells, sights, style. This is better than 5 star hotel. I rarely gush in such positive terms, but this is the most whole and cozy place we've ever stayed at and the price was very good as well.
If we come to Porto again (and we plan to) we will only stay in this place.
