The decor and furniture are pretty worn, but everything was clean so it didn't bother us. Our room didn't have a stand up shower, just a hand held one in the tub. The wifi wasn't consistant and we had to get a new pass word from the front desk every day. The breakfast wasn't great, the pastries were dry. We never saw the bar open and the restaurant had inconsistant hours. Even though this seems like a long list of complaints, I would stay here again. These issues are outweighed by the history and atmosphere, great location and reasonable price.
Hotel Columbus is just steps away from the vatican and an easy walk to piazza navona, the pantheon, trastevere, and the spanish steps. The best feature is the historic architecture. This is a real palazzo, when you stay here you truly feel that you are in Rome. We splurged for a junior suite that overlooked the quiet courtyard. The room was spacious, comfortable, and the air conditioning worked great. Staff are friendly, helpful, and speak english.
