Nuno and Sofia are very easy in communication and gave us all the necessary information even if we didn't meet them off-line. That is absolutely clear how to get to the place and enter the appartement which is rather fancy and nice, full of wood and sun. It was more than enough for 2 people so I suppose the bigger family would feel comfortable there too.
All the devices should we need were there at our service.
The one not that very important minus was that the street is quite narrow and some people living there were gathering right under our windows and made lots of noise once or twice, so it was not critical (critical it would be at Bairro-Alto)))).
So we highly reccomend the appartement and the hosts)
