Iris is 100%++ host, very firendly and very helpful in any issue (although there wasn't any issue during our stay). House is awesome, with outstanding interior design (will keep some ideas, especially from kitchen, for my house), lot of space and bar just downside. The smallest concern is on the bar downside, it is not 100% quite, but very close to this state (so actually I had no sleeping issues, just one night when some visitors were a little bit more loud outside the bar on the street) but this issue fully balanced by Iris hospitality, appartments size and perfect location. 5 min walk to few big supermarkets working till 22:00 (really not usual for early sleeping Berlin), great austrian "Villa Rixdorf" restaruant with 1kg schnitzel (18 eur!) also in 5 min walking distance. Sonnen Allee str. is very close and full of traditional german bars, arabian Shisha bars (7 eur for smoking 2-3 people), and of course give a chance to falafel teller in "Azzam" cafe, as well as Doner :) Except of this there is KINDL in 10 min walking distance (contemporary art center) and Tempelhof airport (you can get a bike and ride through). My best wishes and high recommendations for Iris.
