I stayed here alone while I visited Lisbon for a week and found it was perfect for me. Quite small, but met my needs as I spend my mornings doing a language course and afternoons exploring the city. The kitchen is well equipped with everything I needed for cooking meals when I didn't eat out but had to eat on the sofa at a table which was at knee hight (so not the most comfortable) but did the job. Both bathrooms were great but the bottom toilet doesn't really flush well and chose to use the top one only.
Overall I would definitely recommend this to anyone looking to explore the city and want a nice, clean place to stay in great location which felt safe with friendly neighbours.
