There is a clear winner for this weekend’s open house roundup. If you only have time to see one place this weekend, make sure it’s the Beaux Arts Penthouse in Kalorama. I always figured this building was a co-op. I have never ever seen a vacancy in this building before. I would dare to bet that I would pay well over asking for this beauty and gladly shell out the $600 a month condo fee just to call this place home. Every detail is exquisite. If you aren’t sold, I have included some more modern options and investment opportunities. For more information, email me.
