We are a family of 3 and have stayed three nights at Erasmo 's place. Very central located, everything in near and within walking distance. City 's sightseeing, means of transport, metro, the castelo easily accessible.
Erasmo waited for us patiently after midnight to give us the keys, thanks, Erasmo. Rent the apartment if you don 't mind walking four floors without elevator and the lack of windows and balconies.
