Communication with Helena and Arturo was very smooth. Arturo met us at the apartment and gave us lots of information about Porto, in particular the sights and restaurants. The apartment itself is very nice and spacious for two. It is also extremely well located in the city centre and has a great outlook to a jardim. If I could suggest an improvement it would be to add some lights. The rooms are a bit dark at night, although very bright during the day. Also note that there is no lift so if you are carrying heavy luggage that may be an issue.
