Santis' apartment is great! It's spacious and perfect for 4 pax. It's clean and the interior is new and comfy. The view out of the windows is amazing as you can see the bay as well.
The location of the apartment is really good as well. Alfama is a wonderful place to be with all its small streets and tiny restaurants. It's also very easy to reach the city center and various train stations and tourist attractions.
Santi is a great host and her friend Elsa gave amazing tips around town.
We really loved staying at Santis' apartment and definitely recommend the apartment.
