We spent four nights in Helena and Pedro's apartment during our stay in Lisbon. The apartment is clean, modern and comfortably furnished and we were welcomed with juice and cookies! It is located in a central area of Lisbon and is easily accessed by public transportation and is in walking distance to shops, restaurants and the wonderful food at the ribeira market.
Helena is a very friendly, organized and responsive host. She provided us with lots of information leading up to our visit and was easily contactable during our stay.
I would recommend staying here for the great location, comfort and welcoming hosts.
