The stay at Sofia‘s place was okay. The appartment is small and cosy and there are a lot of nice coffees around. The check-in and out was very easy and Sofia’s mom was very friendly :)
There were some things that we didn‘t like though: the appartment got very warm during the days and nights because of the missing windows in the bedroom and the bathroom. It is also quite dark inside and the place is a little bit run down, especially the bathroom - be careful with the shower, otherwise the place gets flooded.
The place is not directly in Bairro Alto, so in you don‘t mind a walk to the centre or some bars than go for it, but I think next time we might stay some place else in Lisbon for the amount of money..
