It's been said in almost all the comments before, but AtTheTower and Marketa, the host of this specific lodging, were both wonderful. Communication with AtTheTower was very fast and thorough, they also tolerated two changes in the number of guests at late notice (although reasonably it was not a full refund for the 3 days before arrival). Directions to the flat were perfect, and even suggested places to spend some time (café with wifi) before check-in time. We didn't throw any parties of course, but the noise level with 6 people can get a bit high, yet there was never any complaint from Marketa as our neighbor. For 9 adults, especially with grown men, it would probably be too small, but 6-8 young people would fit fine. The apartment was beautiful and very clean, hot water for the tub with nice pressure, the beds were very very soft. There are a total of 3 flat screen TV so perfect for a lazy morning or quiet night. In fact if you are looking for just a place to lay your head after touring hard every day, this place may have too many amenities for you to make use of. The only technical problems were that the dryer did not work perfectly and the wifi had trouble connecting to all our (many) devices sometimes. Thank you Marketa, and AtTheTower!
