We had a super nice stay at Helder's apartment. He was friendly and available at all times for any questions. The place was clean and in a good condition. A lot of things were available (for example everything you need for doing your laundry which is perfectly for a longer stay).
The biggest benefit about the place is the neighborhood. It is not too touristic around but there are a lot of restaurants and bars and the buildings are beautiful! Still the well known districts like Alfama, Baixa and Bairro Alto are in a walking distance. Lovely Miradouros are can be reached within a short walk as well.
