Ruth is a perfectly lovely host, she's very friendly and is prompt replying to messages. The apartment is in a good location, close to the metro and buses, close to cafes and bars etc.
The kitchen space isn't ideal and can be problematic when other guests don't clean up properly. The furnishings are very basic, so don't expect to be able to hang out comfortably, depending on how fussy you are.
Good value for money if you don't mind using the metro and sharing a small space with others.
