We loved Lisbon! The apartment is close to the centre but we actually liked our surrounding area better as there was more character and better (and much cheaper) bars and restaurants than the touristy downtown area. Lisbon is a very hilly city and being located in Bairro Alto you certainly get your workout getting back home. Luckily there is a tram closeby that takes you straight down to the Restauradores square and Uber is very cheap here too. The hosts were extremely pleasant and gave us some pointers our first day and offered to guide us around should we need any help. FYI there is a supermarket called Minipreco at the end of Rua de Rosa which has much more than the tiny shops and isn't too far. Thanks again!
