Except for the location which is quite convenient to downtown attractions and the Golden Gate Park, the entire experience in the flat was less than optimal. There are two bathroom and one of which is very small and under the attic. The worst experience has come from the lack of sound insulation from the ceiling. We were unfortunate to have two groups of people with small childrens who were walking, jumping even into the wee hours. The night before the end of our 4-night stay came the worst. The new family checked in 1am in the morning, literally waking us all up and keeping making all the noises for 3 hours! These we believe are largely due to the lack of good sound proof of the flat. It was a big mistake taking the lower flat. For the entire 4 nights, we didn't have good quality of sleep, quite unsatisfactory for our family who were trying to overcome our jetleg.
