Maria met us at the apartment and wellcome with fruits and port wine. The apartment was quite accurate and had all you need for staying: two bedroms (2 beds in each, one with little window and the other without any window), one living room and one room that has big window faced to the street and is separated from living room with a slide-door.
There is one bathroom and kitchen. All place is really clean and in good condition.
The minuses are high levels of humidity (but you will not recognise this after couple of nights) and audibility which allows to hear each step of the neighbors. There are mosquitoes in Lisbon, so better buy some anti-mosquito device in the supermarket.
Location is perfect - there is big old market 5 min walk - try to have a dinner there or buy shrimps for the breakfast.

I like this apartment and Miguel was really good host.
