We were 4 people staying in the apartment and its annexe during the rainy season.
This is a beautiful, stylish and well-decorated apartment. It's very clean and absolutely well-located on a quiet street, yet 2 minutes away from the Santa Catalina shopping area (pedestrian mall, 2 shopping malls, Mercado Balhao, cafes, restaurants, supermarkets, laundromat, the works).
The famous Sao Bento train station is less than 10 mins away (but be warned, it's an uphill walk with luggage from the station to the apartment). The Mercado Balhao is closed for renovation but a temporary market has been set up just in the street behind the apartment. Please go to support the local stall owners!
Due to its excellent location, we walked everywhere and hardly used public transport, except for Uber to go to the airport, and the touristy transports e.g. tram, funicular train, cable car, river taxi and cruise.
The apartment is pristine in cleanliness, and we were provided a change in sheets and cleaning for staying more than 5 days. Cooking utensils and pots are available, and supermarkets are as close as 3 minutes away for you to stock up on milk, bread, eggs etc. There's no washing machine as stated, but there a couple of laundromats 2 minutes away. Wifi is available in the main apartment, but weak or almost non-existent at the annexe. There's a Nespresso machine and the supermarkets stock the pods you need. There were no coffee mugs initially, but the host were able to provide them upon request. All in all, a great stay at an excellent location!
