We had a wonderful weeks stay at Elsa and Rui's place. The flat is very clean, spacious, and very tastefully decorated - the courtyard being a very nice addition despite being on the shady side.
Elsa and Rui couldn't have been more helpful and thoughtful - always responding within minutes to any queries or questions we had. We had our 2 year old son with us and they arranged a cot without us even having to ask. They also arranged for someone to pick my mother up from the airport who she said was very welcoming and gave her a tour around the city before dropping her off at the flat along with a bottle of wine! Lastly, since our flight home wasn't until the afternoon they also let us leave our bags in the flat for an extra few hours - which was hugely appreciated as it meant we didn't have to lug our stuff around the city.
The flat is also brilliantly located close to the Bairro Alto area - an area known for being very popular and busy for nightlife. There are loads of cafes/bars/restaurants within walking distance , but luckily the flat is also surprisingly quiet at night.
Having stayed in many Air bnb properties over the last few years this is by far one of the best - highly recommended.
