Really very nice location - everything is very close: beach, metro, buses, shops (HortiFruti, ZonaSul etc), restaurants and cafes. Seems to be very safe place. Rua Humberto de Campos is very quite. The apartment is enough for 1 person (for 2 peolpe if you only sleep there). Thaisa reacts quickly to your messages and helps if something happens. There is Internet, though it is not very quick (enough for browser, but not enough for Zoom meetings). I surely advice this option for short-time staying!
