Maria replied to our request within an hour and communicated well throughout - she gave us good directions to the apartment and when we arrived took time to talk to us about our visit and offered us great tips and maps.
The apartment has everything you need my friend slept on the double bed and I slept on the sofa bed in the same room, it was clean and comfortable.
And the area is very, very quiet despite being so close to the centre.
It was one stop on the underground to get to the Danube for a lovely swim on a hot day.
Maria is super friendly and we would highly recommend!
