I traveled alone with two smaller kids. When we arrived in Rome, really heavy rain started. Streets turned to little rivers and thunder was everywhere. We arrived wet at the really nicely located apartment. Unfortunately, the unusual heavy rain caused somehow that water penetrated through the upper floor. Gian Marco was there and took very good care of us. He immediately organized a taxi that drove us to another, even bigger and also lovingly furnished and luxuriously equipped apartment. He personally stayed in touch with us to ask whether everything is okay and really felt sorry. But: no need to feel sorry ;)
We really had two wonderful nights in his apartments. Both were fantastic and really well equipped, including helpful stuff like salt, soap, espresso etc. WLAN was perfect, everything really clean and very tasteful. And the locations were both great with walking distance to Termini and Colloseum.
Would highly recommend!
