Margarida's apartment is in a great location and looks exactly as pictured. it was very comfortable and clean for my month long stay. it is easy to walk to all the key places and is very close to the Rossio metro. I was working there for a month and had some issues with the wifi but she was helpful in fixing it for me. (you're in a a very old part of the city so the infrastructure / internet is old as well and slower. if you're planning to work from here I'd make sure to have a data plan so that you can use your phone as backup). Really nice spot overall, would definitely recommend.
