What an amazing apartment - it has everything you could possibly need ... and probably more, including an incredibly comfortable bed! We also got a bowl of fruit and wine to welcome us. Ricardo's mother let us in and she was lovely - showed us round and made us feel very welcome.
The location is great - right in the centre of the old area, so lots to see and do.
There are probably only 2 things you need to be aware of, depending on what your needs are:
It's at the top of a building, so a lot of very steep steps. This wasn't a problem for us - and got the legs moving ready for the hills of Lisbon!
There are 3 bars at the far end of the road - if you sleep lightly, this may not be the place for you, as people congregate in the street. Ricardo does provide earplugs though! Unfortunately I am a light sleeper and, even with custom ear plugs, the noise woke me each night and went on til 3.30am
