Pros: not too expensive and the location is close to several tourist attractions. Metro stations are so close.
Cons: it is in the neighborhood that looks a bit scary (but in fact after couple days I found that it is actually safe). It can give you some unease feeling at the first day. Then, you got used to it. Since Jonathan and his friends stay in the apartment (his own bedroom and living room), you will hear their voice clearly. So, if you really want privacy, this room may not be the right one. But if you just want to place to sleep at night, it is ok. I got used to the sound and their activity after the first day. So, I was ok with it. The room I rent does not have a lock. It would be better if there is a lock. Jonathan does not speak English but he tries to help and to communicate so I cannot blame much about this.
I had a trouble finding his place since I clicked "get direct" on airbnb. It led me to the wrong location (not far away tho). But I had difficult time since I called Jonathan but he could not respond back in English. Anyhow, a local eventually walked me to Jonathan's place. I was really lucky. If you rent his place, make sure you use the location he typed in for the google map search, DO NOT USE "GET DIRECT" on airbnb.
