Nice neat + clean apartment. Everything looked quite newly renovated and the bathroom was great. This is a tiny apartment that has all of the basics. If you are one who likes to spread out and have all your things out or will be staying quite a while it may not be the place for you because it's tiny, but for most people I think it would work out very well.
Location: on the outskirts of town so you need to take the train into the heart of Vienna, but it was a very easy system to use and goes direct into town. .. took no more than 20 minutes (there's a train stop just around the corner and one about 1/3 of a mile away - the further one is the one we needed for most destinations). I noticed bakeries, a pharmacy, grocery store, and bank all nearby so would probably have everything you need if you didn't want to go into the city for anything.
Check in and check out: very easy and flexible because you let yourself in. This is great if you want flexibility in your day because you're not committed to a specific time and not being a nuisance tying up someone else's day to meet you there :)
Really enjoyed this cute little apartment and would stay again.
