Great for long stays! I stayed at InLx Apartment for 5 weeks since I work while we travel. The apartment is lovely, in a very centric location, and with all the amenities to make a long stay comfortable (kitchenware, extra blankets, radiator, etc). On top of that, it's very well decorated and cozy. The alley indeed can look intimidating but as a female traveler, I didn't have any issues. The only two things to keep in mind are that it can get noisy in the evenings ( I don't have issues with this but some people may find it too much) and that the wifi was a bit slow at some points. Overall it was a very good stay and I hope to come back :)
