We always choose this hotel for our stay in London. Hilton and Hampton by Hilton hotels are usually known for how good and service minded they are. The location is good with bus stops and Waterloo station is close by. The service has unfortunately drastically worsened. We specifically asked at check in exactly what we had to do to not have anyone enter the room. We followed the instructions we got (hang up the sign found in the room on the door), but that still didn't work. Apparently the no cleaning service sign is not the same as the do not disturb sign, but the room was without any do not disturb signs. What they should have said was hang up the do not disturb sign, we would have found it gone, and asked for a new one. When we brought this up the staff were surprisingly unkind and not understanding at all.
The water pressure in the shower was non-existent, it was worse than the showers at gym's that want people to leave quickly. A shower that usually takes 10 minutes took 30 minutes due to lack of water. I tried the three different settings that were available, nothing helped. It wasn't like this before at any of our stays.
The hot breakfast was closer to luke warm, tried it around 7 o'clock, 8 o'clock, and 9 o'clock, no difference. Wasn't like this before.
All in all, not worth it for the location, it's really gone downhill the last few years.
