Alioscia is a wonderful host - he was friendly, attentive, easy-going and informative. He gave us great advice on transport from the airport to the flat, lots of info on places to go to eat, shop, bars, bakeries etc. He kept up the communications through the visit to make sure all was well, and let us leave our bags at the flat until the last minute.
The flat is a joy - clean, stylish and airy, and has everything you need. (Lovely bathroom!). It is in a good location, quiet but with enough facilities close by. The metro station entrance is only 5 mins walk away, but we walked everywhere from the flat and found this the better way to see lots of interesting hidden parts of Rome.
We had a great time and would thoroughly recommend Alioscia and his lovely apartment to anyone. Use the metro if you want to cut down on walking, but access to all the sights is very easy.
