Good room, air conditioning was a little noisy/ has a rattle at lower fan speeds, seems OK on max speed. A/c was missing its swing arm and had sticky tape in place of it. Room was quiet and comfortable, no noise from street (was on 5th floor) however some noise from corridor - doors slam quite loudly. The staff spoke English.
I also ate at the restaurant which was great, although it's not clear exactly where it is (needs better signage, including a sign for its opening hours). The restaurant has a nice wine cellar although not all of the wines on the menu are available. I ordered a (delicious) white wine which was served room temperature and should have been colder. Couldn't fault staff service, which was outstanding.
Be warned though the neighbourhood is FAR from a fresh grocery store and restaurants so it can be a little painful to go out for dinner/ go shopping. There is a shopping mall across the road but this doesn't have a grocery store, only a wal-mart style Lojas Americanas. Taxis wait outside the hotel in the morning though so youc an catch these anywhere you need to go.
