I arrived at 9pm at night and Luis was waiting for me on arrival, which I appreciated greatly! He gave me a good run down of the apartment as well as a map, pointing out landmarks and points of interest. He had also provided me with a bottle of Port wine and two Portuguese pastries (I forget the name of them sorry!) The flat itself is very central to the waterfront and popular landmarks. The interior is very clean and modern. The bed was super comfy and the shower was great!! I felt very secure, being a solo female traveller. He also is very prompt with replying to messages. The only downside I can think of is that there was a bit of construction, so there was a bit of noise from that (obviously this is out of Luis' hands. Pretty much every block has a building with construction going on in Porto!) I highly and strongly recommend Luis' place, and even hope to come back (if Luis lets me!) in the summer time in the future! A very big thumbs up from me!
