We did not get an opportunity to meet Jan but were hosted primarily by his colleague Pedro. Both were very easy to communicate with via email/WhatsApp.
The apartment was a pleasure to stay in. The size is perfect for a couple or a small group of friends, with plenty of space to spread out including a patio, dining area, and living room. Without a doubt the best part about the apartment was its location. It is an easy walking distance to Copacabana, Ipanema, the metro, and bus stop. It is a primarily tourist area so we felt very safe and were close to many good restaurants and cafes. We had a lovely time and would definitely enjoy being hosted by Jan/Pedro again.
