Miguel was a good host. We got to the Miguel's wine bar (directly downstairs from the apartment) after 6pm. We had a glass of wine and some cheese and sausage meat before going up to the apartment. Miguel gave a quick tour and returned to the wine bar.
The apartment is very spacious and has very good wifi. It has all the essentials for cooking, etc. Miguel provided us with towels but has plenty of spares in a cupboard in the hall. He said if we need anything just ask, but everything we needed was already in the flat.
There is a great rooftop area which we went to see the first night but never went back - unfortunately the Lisbon weather betrayed us - but I can see how on a good day you could spend hours up there.
The local area is a fair walk down hill to the centre. You can catch the tram back up the hill or a taxi (which I thought were quite cheap). There is a very cool bar up the hill about 5 minutes away if you just want to sit with a beer and a small crowd. Maybe some people would prefer more central, but I liked the area this apartment was in, close to the Castle.
All and all, this was a very good place to stay.
