Isabel is a fantastic, warm host and this is a lovely apartment in a great location. Even before we arrived, Isabel was kind enough to send us tips and advice and once there, she was incredibly welcoming - plus snacks and information provided on arrival!
The apartment itself is cosy, well-appointed and beautifully decorated. The view to the river is better than the pictures and the apartment is in a quiet and peaceful area (though I'd advise earplugs as at night, sound from the street can seem loud). Though in a quiet street, the tourist sites are within easy walking distance: Bairro Alto is only around 5 mins and downtown probably 15 mins or so.
I definitely recommend this apartment and would stay again, especially with Isabel hosting - she was there for any help we needed and made us feel very welcome.
