My recommend to take a taxi to Sofia place. Specially if you have luggage and walk up and down for nature of Lisbon landscape.
The taxi only 5€ from the nearest train station.
The location is convenient. The famous tram no.28 just right in front of the place or if you wanna go to Rossio center downtown just walk to the back of little street then take bus 714.
Sofia was nice and very helpful. I took all her food recommendations and they were awesome! Very traditional Portuguese food.
The place for us is lovely only bathroom too small and it is a glass door which is ok if you are couple^^
The rest was amazing. Thank you Sofia :)
