Alexandra's beautiful little flat is perfectly situated to explore Alfama and its surrounds - Baixa and Rossio are within a very comfortable distance and there are plenty of easily accessible public transport links to other areas of Lisbon.
The flat itself is on the 3rd floor of an apartment building with no elevator, so be advised if you might have trouble with that! It's quite a climb with suitcases; likewise Alfama is located on one of the impressive hills that make up Lisbon, and the walk from the metro station uphill was exhausting in the midday sun, so be prepared!
All the climbing is worth it though, for lovely views over Alfama, and the flat was a delight to stay in. We had no real problems there, the only thing I can think of if I'm being really picky is that the shower head in the bathroom is at a bit of an awkward angle to be able to wash oneself easily, but that's really scraping the barrel for criticism! Alexandra was a generous and thoughtful host, and we certainly hope we have the chance to revisit her place one day.
