We didn't met Serena (only her sister) but she was very quick to respond to all the messages that we've sent. The room description was accurate and the neighborhood is nice. (We advise to taste the hamburguer at Knick Knack Yoda). We had a problem with the keys but everything was solved smoothly. There was plenty of food for breakfast and everything was very clean. It's a good option for staying in Rome! Thank you Serena!
