I stayed with Ana and Hugo for one week, they are very friendly.
The location is near the train station to the beaches. It takes between 20 and 40 minutes to get to the beach, depends to which one you wanna go. In the train station is also the metro from where you can get to the airport.
A supermarket is near by, even a market hall to buy fresh fruits.
I slept in the little room, which has only enough room for one person I would say. Especially if you want to stay longer. And be aware that the little room has the window to the street, where you can the hear the noise from the street till deep into the night since there are many bars etc.
I recommend taking the ferry (next to train station) to go to the other side. You'll have a great view!
