My wife and I stayed at the Alla Lenz in mid April. Our room was probably the most thoughtfully laid out of any hotel room we have had in our extensive travels. It was comfortable, quiet, with good beds but, best of all, was designed for the traveller (unlike many rooms which are either crammed into old buildings or build to fit the designer's trendy ideas). Good breakfast buffet, friendly and helpful personnel and very convenient parking (lift directly to the public parking beside the hotel). Although not in walking distance to the Ring, the Alla Lenz is one block from public transportation both toward the Ring and toward the Gurtel. We would certainly stay there again when we (hopefully) return to Vienna. Excellent value for the money.
