For hotel very good, high speed of wifi just easy to connected.. Nearby with metro and RER, using M13 or RER C exit bd berthier, walk about 5-7minutes, you will be find carrefour city, just going right way, that's the hotel, but you must extra beware, there is many pickpocket in M13 or maybe the other line.. They are organized.. My wallet was stollen here.. Report the police station, they just give me a reporting paper and there are no solution.. Poor of me..
