Regarding the accommodation, price and location, you'll be hard pressed to find as good as this in the central and south zone at such a bargain. The apartment's very well kitted out and serene with a vista from the work desk replete with foliage, hummingbirds and mamosets.
Security is a running theme for most reviews of this apartment. Understandably as there's a lot of negative press about Brazil. I was also told nowhere was safe in Brazil before coming but having stayed for three months, I can comfortably refute that claim and add that Michael's area is safe and quiet. I felt so safe that after a few weeks i started going out at all hours (even walking to the Gloria beach 20 minutes away at 4am).
As for Michael, he goes above and beyond to facilitate a pleasant stay in his property. And for those who'd like a chat short or long about your stay, Brazil or life in general, he makes you feel more than welcome to engage.
