I came to Lisbon for a city break with my mum and this place was great as there are two single beds, perfect for us. The location is amazing, very close to a lot of the sights (only a 5 minute walk to the Arco da Rua Augusta!), and has great transport links to other places that we wanted to go to, like Belem.
The place itself was lovely, clean, and decorated really nicely. We didn't have any issues with checkin or during our stay, but Maria was a great host and provided all the information we needed. She also sent us plenty of recommendations of places to eat and things to see, which was really lovely and helpful.
There are lots of restaurants around nearby and the cafe across the road does an amazing brunch, so you are not too far away from anything you might need. I cannot recommend this place highly enough!
