From the airport to reach this place, it's easy, 1.45€+50cents card fee. Red line first, than change to green line to Martim Moniz.
The logement is located at the foot of St. George Castle, 2mins to reach green line metro or the famous tram No.28 which gos around the old town:. Metro stop martim moniz, only two stops away from Baixa-Chiado where you will find easily the reputable local pastry: Manteigaria! It tastes better than the most famous one in Belem area. Or you just simply walk to Rossio square where you will find everything you need, the food, the restaurants, the shopping area as well, only 5-8mins away. Very central location. The owner is friendly and amicable. Kitchen is clean and convenient. Big Tv installed even with Netflix. The owner's black cat made my stay more enjoyable. Wifi is very powerful. Only the toilet and shower are quite narrow, but it doesn't bother me that much compared to everything else. Would definitely choose it again if I ever go back to Lisbon.

Strongly recommend a barbecue place called Frangaskeira Nacional. It's not a restaurant, only take-away. Best tasted barbecue ever. I chose Mixta 1: half chicken, one sausage, 4 chunk pork ribs. It costs only 6.9€! You have gotta try home-made chips as well, delicious. I'll go back to Lisbon simply because of it. You can find it out easily with google map.
