We stayed in Rodrigo's place for 4 weeks. Rodrigo definitely made our stay great. He arranged for washing clothes (there's no washing machine in the flat) which came back smelling really nicely, and he sent the cleaner every week to change bedclothes and towels. We also had a problem with the bathroom door not closing properly and he promptly arranged a handy-man to come by and fix it. The apartment is very nicely decorated and super cozy. Even though Rodrigo doesn't live there you can see that he takes really good care of the place. Oh, he also left a booklet with really great recommendations of what to do and see in Lisbon.
The flat is definitely amazing for a short stay, but given we were there for a longer period and were also working from the flat, we would have appreciated some more kitchen utensils and a proper oven. Towards the end of our stay, we were also a bit more bothered about the bedroom having no window and the living room having less natural light than what we hoped for. I would still very much recommend Rodrigo's place and would also go back, but probably for a shorter stay.
