My boyfriend and I stayed in the flat for 12 nights. While we really enjoyed the location (accessibility, access to shops/restaurants/attractions), we would not recommend this flat for such long stays. The street was quite rambunctious at night, making it difficult to sleep (the triple curtains helped), and the kitchen utensils/pullout bed in the living room were not particularly clean (bits of stuck food and stained comforters).
We did appreciate the strong level of communication from the hosts, they responded to any questions we had very quickly and the guide they provided was very thoughtful. We took multiple suggestions for our meals, which paid off!
