The location isn't horrible, but it's not great either. As for the soundproof rooms, they are soundproof from the other rooms, but not from outside. We heard a lot of traffic and city noise, which brings you back to reality while you're trying to escape. I also did not like the fact that after 9pm there is no one there. They have a number you can call for the owner who lives in the building, but there is no one at the reception desk.
The staff were incredible, the room was absolutely gorgeous (we stayed in Rome). We arrived to a candle lit room, with romantic "Rome" music playing, it was breathtaking. We loved the way the room was built around the jacuzzi tub. We could sit and relax, and also watch tv from the tub. Another favorite from this hotel is the bedding, the sheets were so soft and luxurious, as well as the pillows. The sauna shower was lovely. We really enjoyed our stay here.
