We had a lovely stay! The appartement is in a nice little nook in old town Alfama. It's easy to find and only a short (but, of course, steep - don't go to Alfama is you don't like the hills ;)) walk from some lovely Alfama eateries. Tram 28 stops very close by.
The appartement is nice, and has more or less everything you need. It is a little small; especially the bathroom is tiny, and the door doesn't close properly. I would recommend taking a robe/towel and changing in the bedroom.

All in all a nice place to stay, not too expensive and very nice location. One of the best things though, are Elsa and Rui; they respond super quick to any question you might have and seem really nice. Would come back and would recommend :)!
