 Well the room s card was not working properly and we needed to replaced it few times but it could be related to the specific room 
 The hotel staff was friendly and very helpful the room was big enough for 3 adults it was well capacious the beds are great and also the bathroom and the shower Location is great a lot of bars and restaurants are in the area and also central transportation services The neighborhood is great and it was so fun to walk around When I ll come back to London I would definitely take into consideration to return to M hotel
