Antonio is a wonderful host! He even had a travel cot set up for our son which was a very thoughtful surprise.
The apartment is great and has everything you need, it is in a quiet area but there are shops, restaurants and cafes an easy-ish hill climb away and it's a lovely walk into the city - we had a stroller with us so never used the tram!
Check out tasca do jaime and get a beer from the lookout - both really close by.
