Overall, I was happy with my choice. I paid £708 for 5 nights in a Premier Plus room. I arrived around 9:30 am so too early to check in, but I was able to drop off my luggage. I came back around 2 pm, and they let me check in early. I was told there would be a £10 early-check-in fee, but I was never charged for it. I opted to get a Premier Plus room because of the mini fridge and the better wifi. I’m still not sure it was worth it, as the room did not seem much bigger than regular ones I had in the past, and I didn’t really use the mini fridge that much. All the Premier Plus rooms are on the same floor.
The beds were very comfy, but I did not like that you could not leave the bathroom door open (that was on purpose - evidently it’s some kind of rule). The breakfast was good, although I didn’t always eat there, and everything else was fine. The location was great, and very convenient to many of the sights. It was a very quick walk to Westminster Bridge, and a little bit longer to get to Covent Garden (via the Golden Jubilee Bridge). Borough Market was about a 15 minute walk, along with a number of other sights in South Bank. There was an M&S Food Hall nearby, as well as a number of cafes and restaurants, including Gail’s Bakery, which I really liked. It was open for breakfast, lunch and dinner and was a very nice option for getting a quick bite that tasted good. You could either eat there or get takeaway. I would definitely stay at the PI County Hall again.
