We had great nights at London. The flat was quite near from either victoria or pilimco station. Walks 10mins=Flat.
Everything was good. The flat was clean, ample for 2people, and cozy.
Furthermore, you can use the washingmachine right downstair from the flat with 3euro.
However, you will feel like climbing a mountain with full 30inches carriers. Besides, although the toilet and shower room was higenic and clean, the shower booth was too small for big people to take a shower.
Last but not least, the advantages far overweigh the disadvantages.
You will have great holidays in London with the flat.
