Mario is an amazing host. He was very helpful and friendly. The location is in the heartland of the city and very easy to reach by walking. The place is very cozy and tidy. We spent amazing 3 days. There were lots to do near our place; amazing fish restaurants, beautiful sceneries, historical monuments and of course the beautiful Douro river. And all of this places were in 15 minute walking distance. It's an amazing experience starting our day by having a quick breakfast in the local cafe in the street and reading some books in Lello library, eating amazing local fish for lunch, watching sunset in the bridges and having dinner with port wine. And after all of this experience we had a place that felt like home to sleep on but before of course we drank some tea which Mario has shared with us. Once again, thanks Mario. We will never forget you and your amazing place.
