We enjoyed staying at Henrique's place, loved the central location, the lively square and the balcony for morning coffees and evening drinks. Everything we wanted to see was within walking distance (however, Porto is a very hilly city so lots of steep streets and steps - and great views!), with numerous restaurants, bars and cafes in the immediate vicinity. The only negative was the noise in the square during the night (two nights till 3am) which made it difficult to sleep without closing both windows and shutters (we prefer fresh air...).
