Helena's house is beautiful, clean and comfortable. It is located in a safe residential area very close to nice restaurants. We went to Lisbon for an academic conference in the main university campus, and the location of the flat -halfway between the touristic area and the university campus proved to be ideal. Helena as a host is attentive, kind and understanding, keeping in touch throughout your stay without being invasive, and offering knowledgeable tips and help to reach nice attractions in Lisbon and around. I would definitely stay at her place again.
