I can always count on double tree to be charmingly outdated which is what i prefer--very bice hotel, outstanding location right across from John Hopkins, what made me very happy was that despite the valet parking, there was some great restaurants to walk to that was extremely close.
staff was very friendly, rooms were lovely.
I will definitely stay here again.

Make sure you take a room where the air does not blow directly over the bed. The rooms are dark unless you are given a suite. The floors, carpets, and walls need upgrading in terms of markings, tearing, and odors. It was depressing to be there. With a renovation, the hotel would be more than acceptable. It is the only up-market place to stay near Johns Hopkins, so perhaps they are not motivated to spend the funds for renovation.

This is a classic elegant hotel. The lobby is huge and you will want to find time to nest in it's nooks and crannies with a cup of coffee or cocktail. The staff are exceptionally friendly and knowledgeable. All requests, big and small, were met promptly and the customer service exceeded my expectations. If you have business at JHU or are doing the college exploratory visit this is THE hotel to stay at. It is literally right across the street from JHU I would also recommend it over the chain hotels in the harbor area. This is the most elegant and upscale Double Tree I have stayed at and I look forward to another visit when I'm in the Baltimore area.

Stayed at the Colonnade for a business meeting at Hopkins for a few days. The location of the hotel was realistically the only redeeming feature. The decor of hotel was dull, dated and uninspiring. Not only did the plug in bathroom not work when I wanted a bath, but the bath didn't drain when the plug was out!
I've lived in the US for 10 years, and the restaurant served quite possibly the worst ribs I've ever had - and they were ordered on the recommendation from the bar maid! The wait staff was surly, unintelligible and not that useful. Be prepared to seat yourself for a limited breakfast selection - though the breakfast wait staff were really friendly and should be commended.
I think I've worked out where all the old cathode ray tube televisions have been placed...
