Paris and Milano w/friends

I went with some friends, and our first stop was Paris, I´ve been in Paris with my parents and it was great but the experience with friends it´s awesome, nightlife in Paris is a must! We stayed at Couchsurfing; it was a guy from Turkey and he was really friendly, we didn’t hang out much with him but he recommended us where to go. We stayed at Paris for two days, it was the first time of one of my friends so we visited the usual spots but also went to new and different places! After Paris we went to a little village called Annecy, it´s not so popular but it totally surprised me. I recommended a 100% it is so beautiful and has an incredible landscape, we stayed one day but it can be a one-day trip cause it´s not so big. At Annecy we also stayed at couch surfing with another guy, he was also very friendly and we hanged out with him and his friends, they invited us to a party in the mountains so the experience was totally different! Finally, our last stop was Milano, we stayed for two days in a hostel because some of the hotels we looked for were quite expensive, the hostel was great but it was a little bit far from the city center, even though Milano metro is good so it´s easy to move around the city! We traveled by train and the trips were not so long from Paris to Annecy it took us 4 hours, trains can be quite expensive so there are also buses, which are actually a really good option, they are very clean and safe. From Annecy to Milano it took us 5 hours and we had to stop at Chambery, in this case you can also take a bus is way cheaper!
