Well what can I say? Our host Guisi was excellent - her communication was pleasant prompt and exact. Guisi organised our transfer from the airport to the apartment on arrival and we were delivered off to be met by a nice young chap called Nika who gave us a thorough explanation of the apartment and directions to the Vatican. The apartment sleeps 6 but as a family of 4 there was more than enough room for us all. It was extremely clean and beds, towels, toilets, etc were spotless. The location is approx 5 minutes walk from the Vatican museum- out the door, turn right and head towards the steps and you are there - it could not be any handier! From there you are approx 10 min walk to St Peter's Basilica - just follow the wall! Found a fab gelato shop en route where the ice cream was splendid and only 3 euro - would def recommend! From the apartment the Metro is approx 5 mins - out the door turn left, head to end of street towards Medical centre - look left and you will see a Church and the Metro is right of this! Easy! From there Anywhere in Rome is very accessible and cheap to travel around. Our host Guisi even helped to get us back to the airport at very short notice by booking a taxi.
Altogether this apartment is a bit of a 'hidden gem' for location, standard and value for money. Would definitely use again and recommend to friends! Thank you so much for all you help!
