Overall, we enjoyed our stay in Carmen's apartment.
Pros:
1) Carmen is a very nice person, very patient and willing to answer all questions and concerns.
2) the place is very well located, a few meters from coffee shops, amenities and public transportation.
Cons:
1) the place isn't professionally cleaned, not the way we expect from a hosting service anyway. There was mold behind the living room curtains, mold at shower walls, dust in the floor and the apartment and bed sheets had an odor, which I believe it was also mold. I'm very allergic and these things made a difference. We had to clean the apartment, buy new sheets and sleep with the window opened.
2) the bathroom is very small. me & my husband we're very petit, so we had no problem fitting there, but be aware of that.
