The apartment has a fantastic location with a great view. We had a little super market close by, so we were able to make some meals for ourselves, but it's placed in the centre and so we walked everywhere easily! Abu and his friends were great hosts, easily available and they were at the apartment at the agreed time so we could check in. We had a lovely stay in Lisbon.
I recommend going to Sintra if you have the time - it's a trainride away and definitely worth the way.
