This hotel is in a small side street but right in the centre. Buses past the door so rooms at the rear will be quieter than those at the front. The Metro is around the first corner .
Another metro line is 3 blocks the other way. We found all the staff very helpful even to the extent of one giving me his Metro ticket. Beware in local resturants, you have to pay for use tablecloths etc. That's Ok but the charges can be greater than buying new ones.
