It`s a really small place, it's like a 13 mt2. The WC is inside the little bedroom and I was very uncomfortable with the shower, it's better if you wear shoes when you take a shower and it smells a lot of humidity, but it's true that the place is located near several metro stations and it's a nice neighborhood.
Helga was very communicative and responded to my messages very promptly.
I couldn't say that I book it again because for me it's very important a full bathroom.
