I had a nice week in this place. Spacious and with a nice terrasse with afternoon sun.
There is no doorman check-in as announced in the ad, though, so expect the usual hazzle of check-in coordination. As a plus, they did show flexibility on the check-in/out times. Beds comfortable and clean, and nice automatic apartment heating for winter. Bathrooms nice and clean, and plenty of warm water.
Found the floor cleaning a bit sub-standard - might have been a one-off and sure they will fix this for the future. Kitchen very old and the kitchenware not quite clean. Again - hope they will fix at least the cleanliness for the future.
