Our group of 6 was welcomed by Antonio, who took some time to show us around the apartment, and explained different visiting options for our week end in Lisbon, and questions we didn't think of while he was there were answered very quickly by email.
The apartment itself is better then what the pictures make it out to be. we didn't spend all that much time there since we were often out and about, but everything you can need is provided, and 5 showers helped us get ready quickly in the morning or before going out in the evening after a long day of visiting the city.
