 wifi was a bit complicated you are allowed to use free wifi 2 times for 20 min in a day in the room if you want all day hotel requests extra money but in the lobby area it was free so people were sitting in the lobby area on the evenings 
 we have booked a non window room due to cheap price but while check in hotel offered a new room with window and no price difference room has almost everything that you may require no noise at nigths so had good sleeps during 3 days although hotel is not placed in zone1 there are 2 metro lines in 5 min walking distance so we had no transport problem
