I have just had a wonderful stay in Désirée's apartment in Prati. I was there for a week and loved it. The apartment is ultraclean, bright and equipped with all the required necessities. There is no air conditioning, but the breeze from the terrace and two effective ventilators did the trick for me (I am not keen on airconditioned environments anyway). The strong point of the apartment is obviously the terrace, which is quite large and offers great views of part of Prati. I really enjoyed breakfasting on the terrace and relaxing there after work. There were also some great sunsets to watch as well as a fireworks display on my last evening. In fact, you have to be a little strict with yourself or you will end up spending your whole stay on the terrace instead of going out.
Prati is one of the best areas in Rome. It is very lively and there were several good wine bars and eateries near the apartment. I can recommend the wine bar (Enofficina) on the corner. The aperitivo may be a little on the stingy side, but the wines are excellent. I also dined there late one evening and much preferred that to the aperitivo - try the polpetti di tonno, they are very good. Even though there are some good restaurants very near by, my restaurant recommendation would be Trattoria 10-20-30, which is a 10-minute walk from the apartment. The bakery next door is brilliant and the Mercato Trionfale food market is awesome. Prati is very well served by public transportation with a large number of bus lines to choose from. There is also tram no. 19 for going towards Flaminio (where you should check out the excellent small wine bar Cavatappi one evening) and Villa Borghese, and there is a Metro station within easy reach.
Last, but not least, Désirée herself: Désirée is an excellent hostess, she was very quick to respond to my inquiries throughout our communication, and she kept in constant touch during my stay to make sure that everything was in order. She had put a bottle of white wine in the fridge as a welcome along with a delicious water melon. I felt at home right from the start. Perhaps the only disappointment was that I did not get to meet her in person in connection with the checkin, but our communication was so good that I actually feel like I know her well. Her friend Simone did an excellent job with the checkin on Désirée's behalf.
I highly recommend a stay in Désirée's sunny terrace apartment.
