First, there is Leonardo Hotel and Leonardo Royal hotel, I stayed with Royal one, and it is very good. Both are quiet close to the airport like 3-5 miniutes drive.
Secondly, the hotel is super new and clean. You feel comfortable there and free shuttle bus provided. Again, you need to call from the airport to ordere the shuttle bus. I have problem with my phone but I found the Leonardo hotel FREE phone to call--it is in the T2, one of the entrance, close to the entrance door. But again, it seems they will take you to Leonardo not Royal one, but they are very helpful to still drive you to Royal one--which is super nice!
3. If you go to City center, I suggest you to use the hotel shuttle bus to take you back to Airport and take train there. With less stops ,you could easy go to DOM in 15 to 20 miniutes.
4. Again, hotel staff are ALL very helpful and room is clean. Quiet at night, bed is comfortable. You did not hear your neighbour talking which is a good thing.
5. The bar is good, even I did not use it. I have not used the breakfast as I fly earlier.
They all speak reasonable English and that is very helpful.
Again, I should say, the staff, every of them is super professional and they try to help you, espcially the ladies and really apprecited that.
