The stay at Teresa's house was perfect and she's a great host.
The apartment is very nice (a great Portuguese architect from the 60's), beautiful decoration, clean, good energy...one metro stop from the airport, and a nice room for the guests!!
Teresa cared about our arrival, waited for us with a hot tea, suggested a great place to have dinner ...and even after me having broken a vase at her place, she was very nice and polite ;)
The area is very quiet, near "Parque das Naçoes" and connected by metro with the center of Lisbon
Strongly recommend Teresa's place to stay!!
