The inclusion of a stove, clothes washer and dish washer was ideal, but instructions would have been ideal, as I was visiting from another country.
Also, could not understand how to use the television. As an older guest, some things are not that intuitive, as every set-up and place is different. Again, some instructions would have been nice.
While the hotel staff was professional and polite, a dedicated individual for concierge would really be a plus. Often when I went to the desk there was a line of people checking in or out. A second point of contact - someone to answer general questions about my room or Vienna would have been ideal.
Nice bathroom and adequate space for sleeping/working. Very nice ample closet space. Some additional hooks in the bathroom would be nice to hold housecoat somewhere other than the shower.
Finally, I picked the hotel for proximity and price, AND for the pool. The water in the pool was not very warm. And yes, I get it, its a pool! But, it would have been nice to have it warmer for a November day, The sauna was not marked well, as I never found it.
Overall, things went well.
