Ricardo was an excellent host. My friend and I spent a few days in Porto, and Ricardo greeted us upon arrival (with a bottle of Port!) and provided us with a bunch of local restaurant and tourism tips. The apartment itself is in a great location (next to Sao Bento train station and a 5 to 10 minute walk to the bridge/river). It was very spacious, clean, safe and modern. I'd recommend Ricardo's place to anyone visiting Porto, I would definitely choose it again if I come back.
