The location is great- right by multiple bridges and near some nice restaurants on quiet streets away from most of the touristy things.
The complaints I have: the check in process was terrible. I was introduced to three different people and traded off back and forth from each over the course of 3 days prior to check in which was both confusing and really annoying. They wouldn't let me in to the flat finally until 4:30pm, because the cleaner had "many other apartments to attend to."
Then, the cleaning lady plugged one of the many doors you must unlock to get to the flat with paper towel (?), which caused me to be locked in the flat from the inside for awhile!!! I only was able to escape by screaming and banging on the door- luckily there was a construction worker that happened to have a universal key (not one I had, so if even a stranger found me they would not have been able to help by passing the key through a far reaching window) and he let me out.
Less important given the above, the apartment lacks any charm- they really could use a lot more furniture, some artwork, etc. It seems really bare and depressing.
Last, the hot water was scarce and the shower is SO small- as a small woman I struggled even to bend over to get soap off the floor and there is no shelf so you have to be able to bend over. I live in NYC and I know that both apartments can be not so nice with small showers, bedrooms, etc. but this was an exception considering that.
Upside, the flat was clean, safe, and quiet. Note there is no view whatsoever from any of the windows, of the river or the street.
