Without overstating it, I can say that I have never stayed at a hotel or other short-term rental with better service, both leading up to the stay and during it. The communication and the assistance, including the level of depth and detail of each, simply could not have been better (our principal point of contact was Francesca, who embodied the concept of "going the extra mile"). In fact, based on this along, I would consider staying no place else during return trips to Bellagio. Just truly excellent service from start-to-finish.
Beyond this, the apartment was really nice (spacious and comfortable and with good amenities). Lastly, the location is very good.
Again, I would stay here again without even looking at other options.
