Me and my boyfriend stayed in Mun's apartment in September. The original plan was to stay with Mun, but Mun was in the US for work. So it was a shame we didn't get to meet Mun (and her promising travelstories) but we had the feeling that by staying in her apartment with all her pictures, books and travel souvenirs we kinda got to know her a little bit. Good friends of Mun showed us around and they were really helpful with a lot of nice tips (restaurants, the old wall in Girona, beautiful village of Dali!).
The bedroom has its own garden which is great, and you can see the Pyrenees from the balcony on the other side of the apartment. From the apartment it's a 10-15 minute walk to the great old wall which will lead you to the city center but can also take you around Girona, which is unbelievable.
We would absolutely recommend Mun's apartment if you are planning on staying in Girona!!
