Luisa is bubbly and charming. The apt is good by Lisbon standards.
Its very central and also very quiet.
On a down side the shower cubicle is tiny so for a larger person or an average man a bit of a squeeze. Also be aware that the bedding cover and pillows are all feather filled. I have suggested that Luisa change this feature. The heater was a bonus so in winter nice and cosy. The room is spacious but there is only tea and coffee facilities. No microwave. There is also no table and chair to do any work or to eat a sandwich or snack.
By the way seek out the many PADARIA PORTUGUESA restaurants. Cheap and great for breakfast or lunch. Hope this information is useful.
