This is a great apartment in a very convenient location. Spacious, clean, with a well equipped kitchen and some simple amenities for the kitchen and bathroom. Very close to airport bus, buses, trams, underground. Relatively quiet, nice neighbourhood, easy walk to central Vienna tourist sites. Lots of shops nearby for groceries etc, and lots of cafes, taverns, restaurants and fast food outlets.
Charlotte is a great host - she is very quick to respond, and very helpful when we asked to come a couple of hours early and stay a couple hours longer.
A couple of things to note - no TV (you don’t miss it) but excellent wifi. No microwave, but the stove and oven work fine. Bathroom is small but everything works fine - good water pressure and hot water. You just need to physically be able to get into the shower bath. There is a lift, but you need to walk up 8 steps to the apartment door so again take note if you have physical issues. Charlotte supplies coffee (Nespresso), sugar, some tea, salt pepper, oil and vinegar.
Everything is spotless. The bed is comfy.
