The flat is nicely decorated and is ideal for one or two people. In case you decide to stay at Martina's flat, be aware that the hot water is limited, which is absolutely fine but just keep it in mind so that the next person doesn't take an ice cold shower after you!
I've expressed this to Martina already but in case you get easily bothered by the daylight in the morning, I suggest you bring an eye mask with you because there are no curtains and I personally was bothered by this.
