We had to visit London for 2 days for some paperwork at an embassy and wanted to stay near Belgravia, as well as near a tube station. Best Western Hotel offered the best value for money. We were quite happy with our triple room and the facilities provided. The room was nice and clean, everything worked properly. There was a big window, that looked out on the street, but once you closed it, there was very little traffic noise.
Our room was in a different building, from the main reception/dining facilities building, but it didn't bother us much. For me, the fact that going up to our room involved climbing several flights of stairs was slightly more inconvenient. Anyways, our luggage was light, and the lovely young man who showed us to our room, offered to carry it for us. Since, there is no lift, the hotel might be inconvenient for people with mobility issues. However, it is 5 mins walk away from Victoria Station, so one can explore London quite easily, given the transport links. Also, it is easy to go to Victoria Station from Euston train station, in case you are travelling to London from up north, like us. less
