On Praia de Botafogo / Botafogo Beach. The location and the views. Very close to Botafogo subway (Bochemian touch), on the beach, and restaurants and bars within less than 5 min walk. My place is good for couples, solo adventurers, business travelers, and families (with kids). Electrical outlets are US compatible, (and EU, BR as well). 24h security, safe to walk day and night.
The entire place is for you. There is a digital key pad to enter.
I am a academic working in the Bay Area. My homes are Berkeley, CA and Rio, Brazil. I always welcome International scholars and graduate students. I have travelled to 50 or countries myself and stayed a hostels or with friends, but now as I have a home in Berkeley Hills overlooking the three famous Bay Area bridges travelling became less frequent.
