Julio's place is excellent. Very close to the embassy and ASC for those in Mexico for an American Visa. The little businesses around Julio's place are very delicious. There's an oxxo right next door. It was relatively convenient as you could walk to Roma very easily where lots of vintages and shops kept me occupied. It is also close to a few museums.
Spacious. The living room was nice and relaxing and the bedroom is nice too. I love the balcony as well. The room catches nice sunlight during the day and is quiet at night. The bathroom is a bit small but suffices for everything you need. The water heater can be turned on and off which means it is very ecologically friendly, but it also means that you do need to plan a bit before showering. The building is very livable and well-organized. The doorman was really friendly to me.
The place's wifi is a bit slow though. I would recommend coming here with a good phone plan. I couldn't find a water boiler that could come in handy for coffee.
