Cons:Oh boy..where should i begin? i was on a long business trip, checked in for 21 nights. Unfortunately i've experienced more issues in this hotel than in any other hotel i have ever stayed in, not just Hilton.. and trust me i stayed in many of them! Here's a summary of my experience at the HILTON SAN FRANCISCO FINANCIAL DISTRICT: [Air conditioning] At the very beginning, i was given an 'Upgraded' room with a nice city view, a balcony, and a non-working air conditioner. I called the front desk, who sent a technician that fixed the issue for an hour then it died again. The day after, i called the front desk and they sent a technician for the 2nd time, who told me this time that i either need to change my room or let him replace the entire air conditioner unit which will take 2-3 hours. Since it was 9 PM,i suggested he will enter my room during the day while i am at work and replace the unit, the technician confirmed and said he will come back the day after. a day passes by, i come back from work at around 9:30PM , and the air conditioner is still dead. I go to the front desk and they appologize and suggest to replace my room, i agree to do it the day after. [Water leakage] Overnight, at around 3AM i hear the sound of drops.. i turn on the light, and there is a WATER LEAKING FROM THE CEILING directly into my open luggage!!! I had to empty my luggage in the middle of the night and put it upside down to dry. clothes are now wet and stinky! The hotel management appologized and changed my room immediately. The managers (Anthony / Alonso) suggested to take my clothes and send them to the dry cleaning and so i did.. I thought that this will be the last incident i'll have..but of course i was wrong! [The noisiest room] Next, They put me in a new room which had a scenic view to the Bay, but unfortunately located next to the elevator which is the busiest area in the floor. Quickly enough i realized that the Elevator is not the only problem in the room, because right next to the elvator there's the floor's vending and ice machines which was used 24/7 so it was probabely the noisiest room in the hotel. (Who doesn't like to wake up in 2AM to the sound of a coca-cola bottle dropping of a vending machine right next to your door?) In that room (2701) i also had neighboors who: - brought a dog and put the dog in the balcony for hours, - smoked a bunch of blunts and threw the butts on my side of the balcony - Partied all night with loud music (till 4 AM) even though i called the front desk and the front desk confirmed that they will take care of it (which they never did. obviously!) [Keys that never works] Over a week or so, Digital key (Hilton app) wouldn't work anymore. I had to ask for Physical keys, which unfortunately didn't work more than once or twice. Eventually i had to go to the front desk and replace my Physical keys about 5-6 times in a week. [Elevator with a surprise!] At te evenings, you'll enjoy a long waiting line to the elevator. one of the evenings i waited in the lobby for 20 min just to get into an elevator! Eventually it seems like taking the elavator is slower than taking the stairs But that's not all, one day the elevator door opened and a revealed a very surprised couple who had sex inside the elevator!! (March 27th around midnight) So, if your'e into kinky sex scens you might want to wait for the elevator after all. [Overcharged] To make this stay epic - the final reciept shown that i've been overcharged $605 for parking that i never used!!! Called the accounting department and they admitted their mistake. [Conclusion] SOMTHING NEEDS TO CHANGE IN THIS HOTEL! and i say that as a Hilton Diamond club member who spent 100+ nights in the last year only. Due to tis stay, I am currently re-considering keeping my Diamond status, already registered to IHG and Marriot for my next stays.
