Fernando and Fernanda are awesome, warm, engaged and fun hosts. The flat had everything I needed. Moreover, Fernanda is fast at replying to messages. The metro, bank, fruit stands, buffets, restaurants, pharmacy and markets are very close. Every Sunday is a huge, magical market 5 minutes away by foot.
Also, the hosts were supportive and attended a musical performance of mine - Fernando even danced on stage with me.
As much as I loved the flat and its location, be very careful when it rains. Be sure to put down towels by the balcony door. Water may flood into the flat and cause a fall. In my case at 3AM, I slipped, fell and fractured 2 toes - 1 week before my carnival performance.
Nevertheless, I would recommend the place, as experiences differ for everyone - besides it may not even rain during your stay (versus mine of 6 weeks).
