Boutique apartment with all the amenities and close to everything walking. We stayed on the 4th floor but suggest a floor lower which may stay a tad cooler at night.

Loved this apartment! Large apartment with character but with modern updates, high ceilings, balcony overlooking street. In an ideal location and everything within walking distance. Would definitely stay here again.
