I stayed three nights in Frieda and Dahlia's place. I didn't have too much interaction with them, though they are very nice to make our check in and stay easy and comfortable. They location is not perfect but convenient enough because it has lots of tram and bus lines nearby. However, I am still little disappointed by the place. First, it was an old building, and the bathroom smells little mold, towers are pretty worn and the pillows are really uncomfortable. It doesn't look as bright and spacious as the pictures. Second, it was very hot and humid in Rome, however there is no AC in their place. Overall, if I didn't have a high expectation and the weather was nice, it could be a pleasant stay. To be fair, it is not too bad for the price you pay.
