In short: This is a very well placed appartement which I would love to visit again!
The location of the appartement in Lissabon was perfect. Almost everything is in walking distance so there is no need for a rental car what so ever. In addition the host provided us with a lot of useful information and the service was also excellent!
I would totally recommend anyone, wanting to stay in Lissabon for a few days, to check out this gem!
