I visited Rome for 5 days in January in order to attend a conference and enjoy sightseeing. I found Esmeralda's appartment perfect for my stay - it was very big, clean, comfortable and very central. Though I haven't seen Esmeralda much - she was staying in another appartment and I was out most of the time- our communication was always very smooth, friendly and effective. Esmeralda also provided some cookies, jams, honey and traditional Italian cakes for the breakfast, as well as tea and coffee.
During my stay I shared the flat with Esmeralda's friend (who was staying in a blue room) and her cat Orfeo.
I would recommend Esmeralda's flat without reservations and happy to come stay there again.
