Everything was perfect :
1) Lara was very nice and welcomed us personally. She makes everything in order we feel like in our own home.
2) The flat is very well located : near all the monuments, we just used the tram to go to Belem, we walked to every other sites.
3) the flat is very nice, well organised, cosy and clean. Even the bathroom, which is tiny, is so well organised that it's great.
4) Lisboa is a wonderfull city. We spent 4 wonderfull days. There is just a little to much french people (I am french too ;-) ).
We will recommend this flat to everyone.
