We really enjoyed our visit to Ily's place. It's in a fantastic location, close to the Museums Quarter and within walk-able distance of the Centre. There are lovely restaurants nearby - I'd particularly recommend Il Sestante the Italian round the corner on Piaristengasse. Lovely atmosphere, great staff and gorgeous food - and they don't mind you just popping in for a nightcap. There are also plenty of supermarkets if you prefer to eat in. It's fully accessible for public transport.
The apartment is lovely. Clean, bright and airy with spacious bedrooms, a comfortable sitting area and fully equipped kitchen and bathroom. If you're not familiar with the larger Nespresso machines, however, I'd take a lesson before you go - and some capsules.
Communications with Ilana before and during our visit were great - she is a very warm, friendly and helpful host. There was no hassle about picking up and returning keys (from the hairdresser's downstairs) and Ben, her 'man on the ground' (the hairdresser downstairs!) was really helpful and welcoming.
There's lots of information and maps in the apartment and all the essentials you need like hairdryer, ironing board/iron etc so we felt we had everything we needed for a great stay.
If I was going to suggest anything that could've added to it, a simple 'about the apartment' folder would be good, with instructions about heating and the appliances - but we did manage to work it out!
Our thanks go to Ilana for making our first 'girls weekend' in Vienna one to remember.
