I have stayed at Hotel Mimosa in Rome on 4 or 5 occasions, and have never been disappointed. The location (near the Pantheon) is superb, the prices are very reasonable, and the staff always welcoming and helpful. HM is a no frills place--some rooms have shared baths, the continental breakfast is basic, only one computer for internet, no tv. But it is well maintained and clean. If you are looking for inexpensive, basic housing while in Rome, I cannot recommend Hotel Mimosa highly enough.

Let's face it: you're not going to find anyplace under 100€ so close to everything. That said, we had problems with room B, such as insects and what seemed a whole wig stuck in the bathtub drain. Point to the staff, they promptly gave us another room when we complained.
There's nothing much to be said about the place: it's a basic hotel without any luxuries. The only reason they are worth the price is, undoubtedly, the location. If you want to do most of Rome by foot, you can't do better in this price range.

I recently taught a course in Rome and I stayed with a number of students at the Hotel Mimosa. It doesn't claim to be a luxury hotel. It's completely unpretentious, but it is also quite comfortable and extremely well located! It's a family owned hotel and there's a wonderful personal touch in the way they relate to guests. The staff were extremely nice, very accommodating and helpful! We had a wonderful time and would recommend this hotel to anyone who needs to stay in the heart of Rome's historic center!

We stayed here for the location and price, for sure, but here's my problem: My friend and I had just finished a 6 week tour of Europe. For the most part, throughout the trip, were were staying in meager accommodations, as we were on a tight budget. From personal experience, I don't expect a communal bathroom to be the cleanest bathroom, but water flooding every time we showered because of rat sized clumps of hair coming up out of the drain was enough to make you want to throw up while showering. I was sick and wanted tea one day, I had the tea, I just needed hot water, and they refused to let me have hot water from their FULL kitchen. They were the rudest most unhelpful concierges I have ever come across. I understand skimping on amenities to lower the price of a hotel, but you never have to skimp on just being a decent person. I am torn because the location is so incredible, if you don't have a lot of time in Rome, are very low maintenance and don't mind being treated badly, Hotel Mimosa would be ideal if sightseeing is your main priority.
