The balcony / terrace is a luxury. We especially appreciated sitting outside in the morning with our coffee, it was a great way to start the day. The people who rented us the apartment were as helpful and as patient as can be, good to their word and very responsible. The check-out time was flexible and so we could leave in the afternoon without any problem. The location is very good. The busy street you see from the terrace is really two streets over and you are not affected by the noise.
The bed is comfortable but too high up and although a "double" bed it's not so wide. As a couple we found it a bit claustrophobic so close to the ceiling and the wall, so one of us slept on the couch. That said, we both slept well, the mattress and the couch were fine.
This place is most truly best for a single person, but as couple we were fine.
