While my sister and I only stayed one night, Maria's place was comfy, clean, and spacious, and in a great location (very close to the Baixa-Chiado metro station, so it wasn't long of a walk at all to have access to other parts of the city). It had a lot of charm that added to the cozy feel, and all the amenities someone would want and need. Maria herself was so kind and helpful, especially in how to reach her place from the metro and in being able to keep in contact. I would say if you have the chance, staying at her place is definitely worth it.
