The Irmeli flat is clean and very well located in Gamla Stan and super well equipped--it has everything, including a dishwasher, all the utensils you might need (can opener, peeler, etc.), tea/coffee/cereal, etc.! They really thought of everything, and Tom gave us very clear instructions for arrival, which made it very smooth. However, it is important to know that the apartment is TINY and has only one window, which opens out onto the building's courtyard (where the trashcans are), so you don't get much natural light or fresh air. The bed is lofted and in a nook, so if you have claustrophobia, it's definitely not for you. We stayed 3 nights and Irmeli was a great base for getting around Gamla Stan, Sodermalm and Norrmalm, especially since we used the kitchen a bit for breakfast and light dinners. I'd say 2-3 nights is enough for Gamla Stan and for the Irmeli flat. Afterwards (due to availability and location), we moved to a hotel for another 2 nights, which gave us a good mix.
