It's a place I would recommend everyone.
The location is quite close from the subway stop (10-15 minutes with cases) and not so far from the main historical attractions (10 minutes).
There're places you can eat in the very neighbourhood, as well as shops (bakery, pingo doce).
Pedro, the host, will give you some advices at the begnning of your stay. Follow them, my friend, and you will eat good food in a decent prices. Especially on the beach side, he will point you the one and only restaurant where you can eat great sea food for less than 10 euro per person :)
The flat itself is big enough for 4 people. There're 2 bedrooms, a kitchen and a saloon. There's one big bathroom with shower and another one with toilette. In the kitchen you will found all the things you need to prepare your own meals.
The bedroom has a big double window overlooking the street. After closing it it's not so noisy. We sleep there when there was 30 degrees outside and it was fine.
Being there do not forget to buy a bottle of wine and ask your neigbours to drink it with you in the evening :) That saloon has heard some stories, oh yes he had. And maybe this was the best part of staying there. Of course, apart from Pedro's excellent advises.
