LOCATION
My family comes from South Africa and we used to visit there every year, so I know what I'm talking about when I say that if visiting Johannesburg, this is the best part of town to be in (Sandton), and within Sandton, it has the BEST location. It is INSIDE the Sandton shopping center of Nelson Mandela Square. Literally the lobby of the hotel becomes the shopping center, you don't even have to open a door. It is a very safe area of Johannesburg in case that was a worry for anyone. Of course where ever you are in Joburg there's a chance of something happening but Sandton is probably the best part of Joburg to be in, in terms of safety. In all my families years of living in Joburg and my annual visits, nothing has ever happened to me that would put me off returning, nothing has ever happened to me at all. Sandton Shopping Center is very nice and quite large too. When you exit the shopping center, you are in Nelson Mandela Square, which if you are a first time traveler in Joburg is a must see. This is where the statue of Nelson Mandela is. There are lots of very nice and very casual too, restaurants and cafes here. Often you'll see little kids running around outside. (In case of confusion, Nelson Mandela Square was previously known and Sandton Square, the shopping center is known as both Sandton shopping center and Nelson Mandela Square. I just call the actual shopping center 'Sandton shopping center', and the outside of the shopping center 'Nelson Mandela Square'. But it is all the same.)

HOTEL ITSELF
Very nice, large and luxurious. There are a couple of restaurants to my memory, I was there is 2010, and am not exactly sure. Check on the hotel website to be sure. But I do remember, breakfast was very nice, what you would expect at any 5 star hotel. We never ate lunch here, or dinner. But I do think they serve all three meals a day. We actually attended a wedding on this visit to Joburg, which is the reason we stayed in a hotel, usually we would stay with family. But after the wedding, which was quite late at night, the hotel was still running tea's, coffee's and late night desserts in the downstairs lounge/restaurant area. They also had (I think 24hrs), very nice room service, again what you would expect of a 5* hotel.
I am not sure whether or not there was a pool or gym, I am sure there would have been, but take a look on the website to be sure.

SERVICE
All staff are very friendly, and as you would expect at a hotel like this, are there to cater to your every need. Although you don't have to, tips are always welcomed and outside of the hotel, usually expected.

ROOMS
Rooms (or at least the one we stayed in, I am not sure whether or not it was a suite or just a regular room), were very large and of course very nice, clean, and were not 'modern and minimalist' but were still luxurious. With reds and marble and still obviously the crisp, white sheets. The room was quite nice in that it was almost like two rooms, with the bed, bathroom, wardrobe on one level and then a couple steps down and you had a lounge/study area.
The bathrooms always kept in good condition. Marble, or some type of shiny stone cabinetry.

All in all, I think it is the best location if visiting South Africa, very central. They have very friendly and willing staff and good service. The rooms and bathrooms are luxurious and clean and large. The hotel itself is again, very luxurious and grand. And the food as well, very nice.

I stayed in July '10

This review is well overdue as my stay at this hotel was at least four months ago.
This is a great hotel in the centre of Sandton.
The food, room and gym was all great. What really made my stay here was the friendliness and professionalism of all the staff I encountered.
I will most definitely stay here again

If you like 100% attention this is the place to stay, nothing is too much trouble. The staff are fantastic and know how to provide a first class service. The only negative for me on this point is that when I'm travelling on business I'd rather have less fuss (but that's just me) the rooms are very equipped and have all the requirements, I did find the room again a little over fussy but this is the design of the hotel, very decadent. I steer more to the cleaner lines and comtemporary type hotels usually but this was a great experience and certainly one I would recommend. My room over looked Mandela square which was lovely, apart from when you want to stand on the balcony and you're besieged by pigeons, so beware. It's right on the square as well so easy to eat in the restaurants below and shop in the mall, the local Gautrain is in walking distance as well, and you can walk reactively safely from the station to the hotel during busy times.

Full marks for the personnel of the Michelangelo for making our stay a wonderful experience.
Definately the hotel with the best location in the Johannesburg area. Excellent restaurants around. So close to the Gautrain station. The Hotel also offers a shuttle service to the station.
The breakfast is excellent.
