If you're coming to Lisbon with pets, this is a great spot for you, they are very friendly with people in this situation and can help you with a place to store your pet cage within the days you are there - so you have more space at the apartment.
We spend 12 days there (me, wife, kid and three dogs) and it was the best. Great places to visit, good access to metro and a lot of areas surrounding that you can walk your dogs.
Hosts are the nicest people, always on schedule and very good at communications (they have good English, trust me).
