Last updated: September 2026
A neighbourhood (Grätzl) in Vienna's 9th district. Strongest on Public transport and Safety, while Affordability is more of a trade-off.
The area runs on student life; the mood is international and the pace is brisk. Tall, densely built rows of houses line the narrow lanes. It's rarely truly quiet here.
The streetscape is almost solidly Gründerzeit apartment houses.
The six dimensions
Light & built form
Alser Straße is densely and tall built — light falls narrow between the facades, and the lanes turn shady earlier in the day. Measured at the Grätzl centre: about 14.8 hours of direct sun on the longest day, about 5 in December. How bright a single flat is comes down to floor, orientation and courtyard vs. street side — the measurement is for the Grätzl centre.

The roofs above Alser Straße
Within 450 m of the centre, buildings carry around 19 hectares of roof that would be greenable by pitch — 58.1 % of the roof area there, calculated from the City of Vienna’s official roof model. On that area roughly 35,900 m³ of rain a year would stay up top instead of entering the sewer, by the model. The modelled heat index here is 64 out of 100, and with 615 street trees in the same radius the neighbourhood sits below the median of 808 — three figures side by side, not a recommendation.
The radius is a fixed reference area, not a neighbourhood boundary, and the circles of adjacent neighbourhoods overlap — so these figures cannot be added up. Whether any of these roofs is already green is unknown to a geometry model; whether it carries the build-up is for a structural engineer to say. Geometry as of 2016. All districts compared →

Frequently asked about Alser Straße
What is it like to live in Alser Straße?

Where is Alser Straße?
Alser Straße is in Vienna's 9th district (Alsergrund), postal code 1090.
How safe is Alser Straße?
Safety in Alser Straße: Excellent (8.5/10), based on official police crime statistics. A non-binding orientation value for the area, not a statement about any single address.
Is Alser Straße dangerous?
Short answer: no — Vienna consistently ranks among the safest large cities in the world, and that holds across all 23 districts. Alser Straße sits at 8.5 out of 10 on the safety dimension (Excellent). One thing worth knowing when reading such figures: crime statistics count offences where they HAPPEN, not where those affected live. Districts with major stations, nightlife and many visitors therefore collect more reports without a residential street a few corners away being any different. Within a district, the gap between a busy hub and a quiet side street is usually larger than the gap between two districts.
How good is public transport in Alser Straße?
Public transport in Alser Straße: Excellent (9.3/10) – based on proximity to metro, tram and bus (Wiener Linien).
Is Alser Straße noisy?
Quiet in Alser Straße: Average (6.3/10), based on traffic-noise exposure. Part of the area sits along Spitalgasse; a few streets further in it gets noticeably quieter. Right there, traffic drowns out a conversation with the window open (calculated above 75 dB by day). At night it calms down noticeably — the level drops below the threshold at which mapping begins. The busiest named axes nearby, by official annual traffic volume: Währinger Gürtel (~29,269/day), Nußdorfer Straße (~26,275/day), Spitalgasse (~16,250/day).
How hot does Alser Straße get in summer?
In summer Alser Straße is heat-prone — warmer than the Vienna average. Heat index 64 of 100 (Vienna average 57), modelled. Dense, enclosed building form stores the day's heat and releases it slowly at night; there is little green to cool it. This is a MODELLED index (from building form, density, green space, street trees, water and elevation, checked against the City of Vienna's climate analysis map), not a measured temperature and not a count of hot days. Within one area it varies a lot: a green courtyard and a treeless street a few metres apart are not the same place.
How green is Alser Straße?
Green space in Alser Straße: Good (7.5/10). Parks and greenery shape everyday life here.
Who is Alser Straße a good fit for?

It says nothing about which of those roofs is already green, and nothing about statics.
