Saint Shermin isn't a grand hotel with doormen and porters or a lobby where you can have a drink and be seen. It's a small, quirky hotel that's run very well by a friendly staff.
The entrance to the hotel is by a small off-street door that leads into a foyer shared by all the building tenants. A sweeping staircase brings you to the lobby on the second floor. There is a small elevator for luggage or people who cannot manage the stairs.
The staff were friendly, efficient, and helpful. Because Vienna is so easy to navigate and largely available online, we had few questions or needs, but they happily gave suggestions about local dining and sightseeing.
The room was surprisingly large for Vienna and beds were soft but supportive. The decoration felt more like being in an apartment than a hotel room.
Our only regret was never making it down for breakfast. With so many great coffee shops and restaurants in the area, it was a small regret. Vegetarians, vegans, gluten-free, etc.? The area abounds with excellent choices and your carnivore friends won't be disappointed, either.
Transportation is ridiculously easy and available. One of the largest train hubs is a short 3-5 minute walk north and the tram is a block away. The whole city is immensely walkable and we found ourselves just taking a stroll to most destinations, including the Naschmarket, museums, and aquarium.
When we go back to Vienna, Saint Shermin will be on the shortlist of preferred hotels.
