Ricardo's place is beautifully designed architecturally and is in an absolutely perfect location to explore Porto. It is large, well-stocked with coffee and other supplies, very clean, and the host is extremely responsive. The apartment is very quiet with the windows closed despite being in a busy/loud area. The only downside to this apartment is the lack of AC (it gets hot!) and the fact that guests cannot go onto the balcony. Otherwise, a great place to stay in Porto. Thanks!
