The apartment itself was wonderful - big, bright, spacious and offering fabulous extra amenities, such as the courtyard, dog play area, gym, and rooftop deck.
The doormen downstairs were always welcoming and helpful, and the check in and check out process was easy.
This apartment should easily be a five star review, but just a few minor things made it feel a little below the 'luxurious' experience promise.
Some basics: there was almost no toilet paper (as in maybe three or four sheets left over from a used roll!), almost no soap left in the bathroom, and while the kitchen itself was wonderful, at this level you do expect staples like scissors, wine glasses, bottle openers - none of which were available. Again, these are not major issues, and we simply went out and bought what we need.
One other issue which I think probably does need to be addressed, is the lack of cleaning supplies. We had booked quite a long stay (well over a month), and while we understood that cleaning was not provided in the booking, we would have liked to have been able to keep the apartment clean ourselves! The small vacuum cleaner that was provided was utterly useless (literally didn't even pick up loose hairs), and there was no cleaning products with which to clean the bath/shower/sink areas. After more than a month without a good clean, we were feeling a bit grotty. So I think hosts need to either offer a mid-way cleaning service, or provide adequate cleaning supplies.
But overall it was a very positive experience and we appreciated being welcomed into such a beautiful apartment.
