This flat is truly lovely - wonderful location, whimsical in its decor, and the property management a delight to deal with.
Other reviews that caution you about the stairs are not exaggerating. Please keep this in mind when booking. Getting carry-on baggage up the stairs was challenging, but our larger suitcase was a herculean effort.
However, you can not beat the location if you're for something in Old Town, and it was truly a unique experience.
