Sandra was a very lovely host. She waited in the apartment for us, which was clean and very organized. Over all they are very well prepared for guest, there is a handout with a lot of information ready, a map where Sandra kindly showed and explained us everything important etc. Also there was a bottle of whine (which we didn't even drink unfortunately) and towels and chocolate ready.
The location is perfect. In the middle of lissabon, just behind the rossio square.
I wen't with my mother for four days and if we ever vistit lissabon again we would definitely rent Sandras apartment again.
