My group was comprised of two young couples on our first visit to Rome. We lucked out with Hakkahouse. It is beautiful, immaculate, and very conveniently located. I would highly recommend it.
More than the space itself, Simona goes above and beyond to treat her guests well. She is an incredible host; she met us when we arrived, provided us with maps, and lovely snacks. She made the trip to Rome feel even more special. Were I to go back again, I would definitely put Hakkahouse at the top of my list.
