I really enjoyed my stay in Sofia's place. The flat was very homey and was a great place to come back to after exploring Sintra. I loved the tiles on the floor and in the shower and comfy furniture (mattress was great!). The flat was definitely more than enough space for one person and would easily accommodate a couple or a few friends. The flat is not in the historical centre but there are some lovely restaurants/cafes nearby and walking or transport into the city centre or to the sightseeing spots is easy to manage. Sofia was also very easy to communicate with and helpful. Overall, I recommend!
