Royal Residence Haus des Meeres

Very Good
Traveller Type: Family with Young Children
  : It is located in the core of the Mariahilf street, nearby all kind of shopping places, restaurants, etc as well with a short walk to the main points to visit in Vienna. Service was good - we needed some extra stuff in the apartment and they were provided in (maybe) half hour.
  : Mattress had a "hole" in the middle of it. I guess I could sleep because I was really tired from the walking trips. Otherwise I would sleep in the sofa for sure. Time to replace it! Another issue was the internet access. Information was sent wrongly. Anyway the correct credentials were sent after all.

Wonderful

  : Fantastic location in a very cool area, and lots and lots of space in the apartment. Instructions for getting into the property were complicated, but very well explained! Great wifi, we had a very chilled time here as a family. Walkable to all the sights and the local cool bars and restaurants. Loved it!
  : Pros greatly outweigh cons. Very overlooked (but that works both ways). No instructions in the apartment except for wifi (helpful to know about bins, recycling, etc). Very slow firestick TV - not a huge problem as we were out most of the time. Had to unblock the shower on arrival, but fine after that!
