Now this is what Airbnb is all about... By far my best experience ever (of around 20 trips globally).
First of all, Diogo is an extremely passionate guy that both loves Porto and the apartment. When I got there we chatted for about 30 minutes about our lives, the city and the house and it immediately makes you feel at home. The apartment is great for 1-2 people and I love how he created a kitchen and bathroom in such a smart and unique way. Everything is really clean, there are some great treats waiting for you (including fruit, cheese, jam, port wine, chocolate, coffee etc..) that were exactly what I needed after the flight.
The apartment is located very centrally within a minute's walk of some of the town's highlights. It's lovely as a base to explore Porto and doesn't take long to get to for a quick rest or refreshment.
All in all this is a complete proof of why Airbnb is so much nicer to explore a new city than a hotel.
I will definitely comeback and recommend this place to any travellers looking to enjoy one of the most amazing cities Europe has to offer.
