One of the best experiences I've had with AirBnb!
Our host was waiting for us at the apartment when we got there, she gave us a lot of information regarding what to see, where to eat and how to get around (and I think we managed about 90% of the suggestions). The apartment was even lovelier than the pictures (a lot of light, very well ventilated and equipped, and it has a great layout).
The neighborhood is lively but there was absolutely no noise at night (or in the morning, or even at noon). Also if you're planning to walk around a lot like we did, this is the best place to start in the morning and to come back at night - there are many places to get coffee and breakfast and also dinner, drinks and fado. The subway/train station and the supermarket are 3 minutes away. The internet works great, the TV was also very cool (we caught a lot of live concerts on tv during the Super Bock festival).
If you come here, we recommend going to the Pantheon to the very top to see all Lisbon (1 min away), drinking Ginjha anywhere, eating at Sal Groso (2 minutes away) and seeing the cruise ships change everyday (the cruise harbor is right next to the subway station - 3mins).
Overall amazing experience!
Thanks a lot!
