We had a great time in Lissabon, the appartement has the perfect position to enjoy all the best of the city. You can do a lot by feet.
The size of the appartement is good for two and has all the endowment you need.
A disadvantage is that you cannot air out the place. But anyway we had a good time and can recommend the place for a short stay and people with average requirements. Claudia is really nice and well organized, check in and out was uncomplicated and her reachability was great to.
