Benjamin's studio was really in the "heart of the Alfama" neighbourhood. Along with its great location, it was a well equipped flat with all the amenities in the kitchen and well functioning appliances. Although the place was a tad bit small, it was clean and cosy, and made it a comfortable retreat after a long day of sightseeing. It seems like the periodic nightly noise (e.g., barking dogs, cars/trams) were all a part of the day to day living in Alfama, so if you are sensitive to noise, just be warned.
Benjamin was a great host, from providing us information about the goings on in Lisbon to ordering us a taxi to the airport on our last day. It made our holiday all the more enjoyable!
