Casotas 6 is exactly what the airbnb site says it is. Small, but fine for one or two people. It is simply furnished, but everything is clean, modern and works well, including the electric heater (which is not always the case in Lisbon). The kitchen space is adequate for simple cooking. There are several restaurants nearby as well as the Pingo Doce supermarket and a mercearia (traditional grocery). It is also tranquil, despite being in the busy city. Good public transport by metro (about 10 minutes walk) and bus (closer). Maria is an attentive host and always on hand when you need her.
