This flat is in an excellent location. 2 tube stations are close. We only used the Vauxhall station. It was about a 5 minute walk over the bridge. Also at this stop were various grocery stores and coffee shops which was also convenient. We walked to Westminster Abbey in about 15 minutes which has you in the heart of many great attractions.
The flat is located at a busy intersection which I only note because we had to sleep with the windows open. The air conditioning was not working and wasn't able to be repaired during our stay. The street noise was considerable through the night. This is likely because we were next to a bridge which meant it was busier than other streets may be at night. Since we were jet-lagged the noise disrupted our sleep, but with the windows closed the street noise wouldn't have been an issue.
The kitchen was well equipped, as were the bathrooms. The rooms were spacious and comfortable and we enjoyed the views out the windows. The doorman was present 24 hours a day and very helpful and friendly. We forgot to bring an electrical converter for our computers so ordered one online. It was delivered right to the door of the flat which was very much appreciated. Veronica accommodated our early check-in and all communication was very efficient.
