The apartment was perfect, clean, well decorated and well located near to the tube station, supermarkets and the bus stop. It was exactly as it looks in the pictures.
The only 2 downsides were that there is no heating and it can get cold sometimes, and that the shower on the main bathroom was blocked so water was acumulating.
If you go with your car there is a private car park in Praça do Chile, for 10€ a night and it is just 3 mins walking.
