My stay at Marta's place was pretty enjoyable. Marta was very friendly, happy to talk and flexible on check-in and check-out. Although the flat seems to be under repairs, the room was clean end cosy, with a nice view on a bit noisy street lined with trees. There were no locks on the room or on the bathroom, but that wasn't a problem for me.
The flat itself is located in a calm residential area some 30 mins from the city center. Make sure you take a bus to get there, otherwise it's a 25 mins walk from the underground station!
