The apartment is located in a nice and quiet neighborhood, with little restaurants which are great for lunch or dinner.
Although we didn't meet Helena she provided us with loads of information about the touristic highlights of Lisbon, she even asked our interests to make it more specific for us. Furthermore, she sent us a couple of emails to ask if we were okay and Helena also called us. She made us feel welcome.
The apartment itself met the description in the advertisement. On the warm evenings the airco was good for refreshment. All in all we enjoyed our stay.
