Overall, a great experience, as someone would expect from any Mercure hotel.
The only downside was the kettle in the room. It wasn't working and they didn't fix it after I mentioned about the problem.
The best part here is the location. You're a stone throw from Japan House, Itaú Cultural, SESC (all culture-based places).
Paulista Avenue is the main road in the city, bringing together many shopping centres, cafés, department stores and the best connection via underground to most of the city centre.
