I am very happy to share my recent experience at Wikirome.
Host: Roberto was very kind and highly responsive. I had several questions before and during our stay. Roberto's responses were very prompt and he provided very helpful answers. He even called a museum to see if it was open!! You cannot ask for a better host. When we had a little issue with a taxi driver, Roberto really spoke up and was quite on our side to help us out.
Location. This is in my opinion one of the best. The metro is a 2 min walk, Vatican 10 min; buses in front and for a large metropolitan city quite an acceptable level of noise. We had no issue
The apt is quite convenient with large bedrooms and other conveniences as described. Quite clean and well maintained

I will strongly endorse the place for anyone
