Joao is a very compassionate, friendly and knowledgeable host. From the beginning, he was very communicative with us and accommodated a last-minute reservation change due a health condition of a traveler in my group (even though he did not have to). His on-boarding process was fantastic - he met us promptly upon arrival (and even helped us with bags beforehand since we were struggling :) and patiently explained everything we needed to know about the apartment, the neighborhood and Porto generally. Oh and there was wine waiting for us! The apartment fit our needs very well, and was perfectly situated in Porto - amazing views and close to shopping, restaurants and the waterfront.
Highly recommended!
