The apartment is very spacious and stylish. It is wonderfully situated and we chose to walk everywhere in our few days there as wandering through the streets of Rome was also part of the joy of the holiday. The beds were very comfortable and the bathroom was perfectly good. Be aware that it as an overbath shower with no screen/curtain so controlled splashing is necessary. Plenty of towels were provided and the water was hot and suitably pressurised.
Most of us don’t plan to cook vast meals when we are on holiday. The hob was very quick and boiled water at speed. Us Brits have to remember that water boiled in a saucepan can still make tea and that no kettle is not a problem! As advertised, it is quite a climb to the apartment, up an inner stairwell. Factor that in to your planning if you are older (me) or have mobility issues. It is worth the climb, however. The little local food shops are very handy. One block over we found a lovely delicatessen selling bread, cheese, salamis, milk etc with really friendly staff. The same distance away, Pizza Re was also very good and open until midnight. If wifi is important to you then it was available at the front of the apartment but not in the back bedroom. There are good fans in both bedrooms. Keeping the windows/blinds closed through the day and airing the flat at night meant it did not get too hot for us (mid September). Luigi was very helpful in arranging a taxi to and from the airport. We were significantly delayed in arriving but managed to meet up with our driver. In terms of cost, both money and time, taxis make the most sense if there is more than one of you and you can afford it. If I ever return to Rome (and I’m supposed to, having thrown the right number of coins into the Trevi Fountain) then I would be very happy to stay in Luigi’s place again.
