This is a really beautiful apartment exactly as shown in the photos and it was spotlessly clean for our arrival. We were warmly welcomed by João & Andreia and given tips for places to visit - also there was lots of local information available in the apartment. Although we didn't have the opportunity to cook during our short stay, there was plenty of crockery and utensils should we have chosen to do so.
Porto is a very walkable city, and the apartment was only a few minutes walk to the main shopping street and the central train station. We ate from a very local (same street) coffee shop, tapas restaurant and bakery - all good. However, we also covered most areas of the city and didn't need to use public transport (apart from getting to and from the airport) at all. It felt safe to walk around - and also the apartment is in a house set behind the main street, so it is very secure.
This was my first airbnb experience and I fear I might have had the bar set far too high for future stays elsewhere!
