The place was clean, in a good location - central enough to be easily accessible via public transport, but also away from the main roads to be comfortably quiet at night. Please take note that while it is close to main bus and tram stations, this area is not walking distance to the main tourist spots in lisbon (praça do comercio, rua augusta, etc.) - to get to these or other places you will definitely need to commute.
The best part about our stay with Vasco is that he is always available to accommodate any of your questions or concerns. He is very warm and quick to reply.
All in all we had a great time in Lisbon staying at this apartment. Muito obrigado!
