I find some of the former reviews to be unfair. The area around Termini station is not the most upscale, but it is not dangerous and for a lot of us who are in Rome for a limited time, the convenience of being near Termini is huge in terms of efficiency. The Concorde is a couple of floors of a high rise building but many, many hotels that handle tourists in Rome are the same, in fact it is typical to find 3 or 4 hotels in the same building, just different floors. This hotel is quite clean, you can absolutely come and go at any time and so what if you have to ring a bell to get the attendant in the middle of the night? That is most small hotels in Europe. If you want American hotels then stay in America, this is Europe and things are different, not necessarily worse but different. Criticizing this is unfair. Breakfast was better than most Rome hotel breakfasts and coffee/roll etc is typical breakfast in Rome for any hotel. And it is good and served with a smile. As for carrying luggage up the stairs, there is an elevator, you just might have to wait for it some, so what? To me, it is clean, central, comfortable, I was treated well, it is not unsafe, it is fine. I was traveling with my kids and they liked it, I never felt they were unsafe, but then again I didn't have them out walking around in the middle of the night. You do have to watch the pickpockets here, even more than elsewhere in Rome, which is famous for pickpockets...watch the little kids, that is who does it.
