I had the Single room apartment in Rua Martens Ferrão 26, which was very cosy. The bed is quite small but it was ok.
The apartment is located close to the main street but it was very calm. public transports are close. if you like to walk you can reach the old town easily by foot.
nearby you find a lot of supermarkets and shopping malls.
big weekpoint of the apartment is the cleanliness. no one cleans the fridge, there was a lot of rotten food, also in the kitchen. the rubbish bins where overflowing. if you like to cook at home you should be aware of this
