I stayed at Valentina's place with my girlfriend for 5 nights. She answered quickly and was easily reachable when needed. We arrived earlier than expected and she came to us in 10min.
The house is very nice, with all comfort; kitchen is full equipped (it misses the dish soap but I presume not everyone will wash the dishes, anyway!). Having two TV is quite interesting, still, it lacks the multimedia part (Wii equipped but no batteries in the remotes, no DVD player or so; same as the dish soap, it will be a good plus).
The sleeping room is nice, soft lighting, big wardrobe, big soft low bed (maybe too soft?).
There's also a big bathroom with toilets inside. Nothing special here, we enjoyed the large mirror.
Globally, all the rooms are well decorated and looking modern.
About the situation, it's just in front of the line 11 bus, it will take you to the center in less than 10min. Nearby there are also a cafe that sell tobacco, bus tickets and various services. Just there, another bus stop for bus lines 36&37 which will drive to the center too. The pizza restaurant situated in front is also a must stop!
We rented a car from the airport, and it was safe and easy to park around. Great experience with Valentina !
