You cannot beat a location like this one, and I want to say that more than anything, this is the major bonus of this rental. We walked everywhere in Lisbon, and were steps away from the train station to go to Sintra, and the one to go to Belem. There are plenty of very cute local little restaurants right above the apartment, but you are still miraculously far from the crowd of tourists.
Another major plus is the impeccable cleanliness of the place, and more than anything, Silvia and Arlindo's hospitality. We did not even had to think about how to get there from the airport. Silvia came to pick us up!
Just be warned, this is a very small place, and the toilets are located in a closet, right next to the bottom of the bed. Your bathroom experience can be very sexy when you are two in the apartment, but luckily we both had noise canceling headphones... This may be a bummer for some, but if like me all you care about is convenience (well located, super clean, easy to access, safe), and do not plan to spend a lot of time locked in the apartment anyway, this is a great option.
