First of all, Miguel is a superb host. He was very flexible and communicative, and supportive in everything we needed.
The apartment is very well located, 5-10 min distance from Rua Santa Catarina. But it is in a quite area, so we weren't disturbed at night.
The place is very nice, big, very well equipped, and comfortable. It has two toilets, one in each floor. The one on the top floor, where the bedroom, is quite large and has a very nice shower. It also has one AC/heat pump per floor - we just tried the heat and worked very well. It has also good WiFi so I could work a couple of days.
We enjoyed it very much. If I have to look for something that could be improved, it might be the mattress; it was big, but not top quality - but it was not a big deal, as I found it comfortable enough.
In summary, great place to work remotely, rest, and discover the city. I definitely recommend it.
Thank you very much, Miguel!
