We had a great stay at Irina's tiny but lovely appartment. The warm mat and the nice bed were really appreciated.
It is in a very cute area of Copenhagen (Nyhavn small Harbour), the perfect location to walk around the whole town and to have a mulled wine at the bars down the street. Even though the bars are open late, we heard no noise from the room upstairs. Note that there is no hairdryer if you need one.
We are very happy about our stay there and recommand it 100%.
