My husband & I really enjoyed our week at Susana's place in Porto. The apartment is centrally located so most everything is in easy walking distance. It's also easy to catch a train, metro or bus if you want to venture further afield.
The apartment has everything you need for a comfortable stay. The bed is super comfy and the shower steaming hot. Moreover, the kitchen is well equipped so you can happily self cater if you like to cook. The terrace is real bonus for somewhere so central - if we'd been here in summer we'd have eaten every meal there!
