I had a wonderful stay at Diana's place! She's lovely, fun and will make you feel very confortable in her place.
I also enjoyed a lot the apartment. It's modern, clean and very quiet. The temperature was always good even if I was there in August.
The location is great too: very nice, safe and lively neighborhood where you'll find everything you need. There's a metro station just a couple of minutes away but I was mostly walking to everywhere I needed to go.
I definitely recommand!
