Loved the location, still close to the more touristy spots but quiet and charming enough to feel like a getaway with lots of parks and museums right nearby. The terrace was my favorite part with those river views you couldn't beat.
I stayed alone for 3 weeks working remote from there and was very comfortable in the space. Wifi was good too and nice to have a dedicated table/work area.
However, if you're really planning to use the 2nd bedroom just be aware that it's quite small and I think because the building is so old, it weirdly would smell really bad at times. The main bedroom is definitely a better bet for good sleep.
Marta was easy to communicate with and I would recommend this spot, especially if you mainly need one bedroom.
