We had a lovely time in Lisbon, and in Alexandra's appartement. It's a tiny place but ok for some days. Not ideal for tall or heavy people, or light sleepers. The only thing to note in terms of cleanliness is that the edge of the shower was a bit moldy. Otherwise you have everything you need in a very pretty neighborhood (the most historic part of Lisbon, I think). Alexandra is very accommodating and replied really fast when any questions arose.
