First of all, I must say that the location is perfect. If you are coming by airplane, you can take Leonardo Express and without any delay or stop, you will be in 30 minutes in Termini. You just take right exit to Via Marsala and within two minutes you will find Paolo's place.
Place is also very close to main historical and important places in Rome that a visitor must see, namely Colosseo, Foro Romani, Piazza Navona, Vittoriano, Vatican, Maria Maggiore and St. Giovani in Laterano. All these places we covered with walk and saw some extraordinary pieces of mainly Renaissance architecture - buildings, streets, piazzas etc.
Apartment is very clear, tidy, comfortable, located in safe neighborhood. Paolo's immediately responded to our arrival, came and waited us in front of his apartment. He was able to come in whenever time we needed him.
Thanks to Paolo and I am sure that people coming after us will share similar positive experiences.
