Our stay at Sergio's home was absolutely marvelous and I would sincerely recommend it to anyone coming to Rome. His place is close to the central station, walking distance from Colosseum and Roman Forum and next to a metro stop and multiple tram/bus stops.
Although we arrived late in the night Sergio received us with a warm welcome and gave us abundant information about the city, it's most important sights and some recommendations for where to eat. These are definitely worth it because the restaurants he pointed out were by far better than the other places we went to (without being more expensive at all)
The room is beautiful and perfectly clean, since the building is old and we stayed there end of march it was a little bit chilly when undressing at night, but that is made up for by the fact that the bed is covered by a luxurious feather blanket and feather pillows which were so soft and firm I would have loved to take them home :P
The bathroom is all to yourself and has a shower, a separate bathtub, toilet and bidet. The water for the shower and sink are connected, as is common in older buildings, which meant that the shower got a bit colder when my bf was using some warm water to brush his teeth at the same time but that is a very minor thing and easy to work around. Otherwise the shower runs nice and hot after a little time to heat up. Everything was again spick and span clean and the towels were also nice and large.
All in all there is nothing negative to say about the house itself. Late at night you might find some shady figures around the metro entrance but that is likely to be the case all over the city at night.
Sergio is a very polite host, available at all times and really superfast in responding to messages, it was a pleasure to stay there and the breakfast that was included in this stay (consumed at a café one block down the road) was also tasty and typically italian.
