Irene's flat is very nice, clean and comfortable. Alfama is a nice barrio to stay, so many good restaurants and quiet area. Saturday morning takes place a market just in front of the flat and it is very interesting to visit (and not noisy at all!).
We arrived quiet late and Irene was waiting for us.
The only point I can say something about is the main bed, it is not very soft, for my taste at least!
I recommend this flat for sure.
