Happy 6 is an exceptionally clean, modern, and well designed apartment with many thoughtful amenities (laundry soap, basic toiletries, coffee pods, etc.). Joao was very friendly, accomodating our changing arrival requests and welcoming us with multiple recommendations on how to best experience his beautiful city - from restaurants to sightseeing to shopping - making our stay all the more enjoyable for his input. The apartment is conveniently located - about a 15 minute walk - to all of the major attractions and provides a quiet, comfortable base from which to explore. I would definitely recommend this apartment with one warning: the second (ensuite) bedroom located in the upstairs loft has very narrow, steep stairs that could prove challenging for some.
