Paul was welcoming and helpful. He gave me a map, went with me to the shop to buy the transit card etc. Even though he lives in a different building he was there pretty much every day cleaning and looking after maintenance issues.
The room itself is quite basic but comfortable, there is a high skylight, but no window you can see out of. Remember to bring an eye mask if you are woken my morning sunlight as there are no curtains (pretty normal in south america). There is a good wifi connection.
I liked the neighbourhood. There is a ecological park 15 minutes walk away if you enjoy running, and the subway is just one minute away. Loads of buses around. Basically its perfect.
