We stayed for 6 nights in August and found the location just perfect! With Principe Real just up the stairs - no other way in Lisbon - we were really close to many restaurants, bars, exploring, transport etc. The apartment was very charming - sure 3 flights of stairs were tough on the way in but the view from the top was more than worth it. Nice and bright throughout we loved having morning coffee and evening drinks on the small but gorgeous balcony overlooking the castle and city. We were just 3 but it would still be comfortable for 2 couples and a child or a couple and 3 kids. Many other areas would be more in the thick of it but ours was just 5-10 minutes walk from the full on busy Barrio Rialto but so quiet and a real retreat after a busy day walking. air conditioning a treat after the hot days wandering. Would recommend CAT's place for sure. Lisbon was an amazing experience for our family. thanks for making it all the better Catarina.
