Almir was a great host - he met us as we arrived, and immediately took the time to show us the grocery store and bakery nearby. Very responsive to messages, and helpful with recommending the best route to get from the airport to the flat. He also very kindly left some local beer behind for us to enjoy, so he definitely went out of his way to make sure we felt welcome.
The flat itself was a good size for our party (we were two), and had everything we needed for a weekend trip. Everything was spotless. Plenty of reading material around for the curious mind.
Location wise, I think it is also perfect for a city break - not right in the city, but easy to get into the centre by U-bahn, but then quiet enough in the evenings that you can rest and recharge after a day of 20,000 steps to do another 20,000 the next day.
