Overall our stay at Rodrigo's flat was fine! We never met him, but he wrote very nice messages, always replied instantly and brought us a fresh set of towels as soon as we asked if it was possible to get some after a few days.
What we weren't completely aware of however is that the flat is on the ground floor and because it isn't very well isolated (can be quite cold during winter months) you always had the feeling the person or car was right next to you as soon as they started talking / honking outside. Also, the garbage collection truck comes by at like 11 at night..!
Furthermore the bathroom and kitchen could have been a bit cleaner, but it also might be normal for Portugal and maybe it was just us expecting a bit higher standards..
Nevertheless, considering how nice Rodrigo seemed, the price and distance to the city center, I would probably still recommend the apartment.
