Host: Probably the most friendly and the coolest host you will ever meet with Airbnb, Marcos is awesome and very accommodating. He also offered me a lot of good suggestions for place to visit and even an umbrella when it was raining outside.
Sometimes his friends may come over but there is a door separating the kitchen and your room and the living room, so it's not a problem at all.
Location: The location is not close to any L train line but many bus lines go there: 94, 66,65, 49 etc. Walkable distance to Ukraine Village if you want to check out the little art museum there. The Humboldt Park in the neighborhood is pretty nice too.
Room: A cozy small bedroom, enough for one to two people. There is a plug in heater so I stayed pretty warm the whole time. Also there is a small fridge for your food and drinks.
