Hotel Rafayel is very new and clean. The Mississipi room was very well appointed if a little small. The shower was great. There is a small cupcake boutique in the lobby which lets you have free tastings...and they were great.
Very helpful and friendly. One of the strengths of this hotel.
Not great. It is on the River Thames, but the neighbourhood is semi industrial which was odd. The train connections are also not good, with a 10min walk to Clapham Junction. The hotel does offer a great (and free) taxi service to the train station. The best public transport in the 170 bus which stops outside the hotel.
Overall a good hotel, but if you want to see the sights and shops in London, i'd go for something a little more central.
