Ana is very kind and Silvia (the concierge) was always available and very helpful during the stay. Great communication. The apartment looks nice and modern, with good standard and is very clean - just like in the pictures. They even left some drinks in the fridge and small snacks for breakfast, which was a very nice gesture!!
Nevertheless there were two things which bothered me:
1) The strong moldy smell in the bathroom, as also noted by other guests. It had to keep the door closed at all times, otherwise the smell would spread throughout the flat.
2) The street & surroundings: Whereas the neighborhood itself is central and convenient, the street where the flat is located is odd. It's isolated, dark, dirty and there's a strange group of men around the corner 24/7. I was traveling alone and didn't feel safe, it would have been helpful to know this upfront.
