I stayed at the Holiday inn in Southwark as a cheap overnight before catching the Eurostar to Paris.
The hotel is OK, a little small but the free breakfast is a nice touch.
Its a fair walk from the nearest tube station and there is nothing close by if you are visiting at the weekend everything is closed.
Taxi to Waterloo is about £10 and takes only a few minutes.
If you are visiting the west end then a hotel closer will be a better option.

Although this hotel IS in a great location - good for Waterloo, Tate Modern, etc. The service is really not good. The staff were rude, off-hand and very unhelpful. The bed sheets were stained with what looked like blood. The bathroom fittings were bad - hot water coming out of the hot AND cold taps in the sink, broken tiles, shower that kept going icy cold. Un-hoovered floor. Noise (very loud!) from either air conditioning or bathroom ventilation - meaning no sleep. The buffet breakfast was ok but the room was so small, they had to open up a meeting room to accomodate everyone, and then they kept running out of food!! Will not go back to this hotel, ever.

Not sure I can recommend this as a place to stay. I drove there and needed to park for 5 minutes to unload 4 children and 6 bags and front desk clerk was not particularly helpful about where I could park. She wanted to charge me 12 pounds to park in their car park to unload!! Rarely a smile from anyone, it appeared to me that they are just working for the money and not for the love of the hotel business.
Having said that the maid was lovely and immediately set our room up as a triple as soon as we arrived. However, the beds are awful and the noise from the front of the hotel kept us awake. My friend stayed at the back of the hotel and she was kept awake with chatting outside the hotel.
Bathrooms were okay not sparkling clean and only with a shower.
Breakfast was great, especially for the kids.
Location okay and an easy walk from public transport.
Not sure I would go there again.

We stayed here to save a bit of money while in London. The bus and tube lines are close by. The reception area/breakfast area was a bit frumpy but the breakfast service was good. There is a bar here at night for guests so you don't have to leave again after a long day sightseeing. We were able to stash our luggage for the day until check in which left us time to sight see. The room is small with not many frills but adequate. Tea and supplies in the room was nice. Internet on their computer in the business center can get pricey.
