Gustavo was very helpful and provided water/bread/juice plus towel and clean bedding on arrival. He also ensured that I had wireless Internet and he was available if needed. He spoke great English and that helped as very few of the people I met in Rio speak English. Very nice guy! The apartment is about 400m from the beach in Flamengo, 50m from the main San Salvador square where there is a small supermarket, some cafes and a pharmacy.
The apartment was as described - including very powerful air con, fridge, single-ring cooker, coffee machine, washing machine, shower and toilet. The shutters are very effective at keeping the apartment dark and relatively cool. There is a double-sofa bed and wardrobe. All you need! San Salvador square is only 50m away and is a very popular square with locals, particularly after dark. Weekend activities last past midnight, including live bands and hundreds of people. Very good apartment, great location but not if you want peace and quiet! Taxi driver did not know the road - but just say 'Praca San Salvador in Flamengo' and they will find it easily.
