Denise's place is great. The studio is small but very well laid out, and the large terrace makes it feel much bigger. The bed is comfortable and everything is very clean. The terrace is amazing, great for drinking wine and watching the sunset. Denise was also very flexible with me for an early check-in and late check-out, which I am super grateful for.
It takes about 5 minutes to walk from there to the metro but you should avoid walking late at night. The rest of the day it's fine. You should be aware that the apartment is close to a favela but very safe, due to the fact that it's in a secure gated block. However, some Saturdays there are parties in the favela, which can be very noisy, so bring your earplugs.
Overall I loved my stay at Denise's studio, and it was amazing value for money.
