My stay at Rui's apartment went without a hitch. Rui is the most accommodating and responsive host I have met, and was very flexible to our needs: in fact since my parents and I arrived at Lisbon early in the morning he was able to check us in well before noon, and likewise he was ready to let us checkout later on our last day if we so needed, which was very kind of him. The apartment is beautifully decked out, the kitchen has all you want and Rui even left some necessities in the fridge for us on arrival (including beer!). The location was very ideal too: on a quiet side street just off Rua do poço dos Negros, it was between the busy and quieter parts of the city (so you can choose as suits you!), you can also catch the 28 tram going to the castle and around the hill back into town, AND it's near the Santos train station with trains going to Belem (tower of Belem and the discoveries monument) and to Cascais closer out to sea. Besides, during check-in Rui gave plenty of suggestions for places we should go. I cannot recommend Rui and his place enough, I am sure to visit again!
