Jonathan's place is perfect as your home base for a London adventure. The room is well decorated and very spacious for two people. Room was super clean on arrival and Jonathan is very responsive.
There is another room directly across from you who you share a bathroom with. Bathroom was very clean and had plenty of soap and shampoo.
The building is beautiful and you have a nice view of the street and backyard. Since the house is older, sound travels easily. Street is pretty quiet at night, but you may need earplugs if you are a light sleeper.
Walk to the tube is a short 10 mins and there are a few nice coffee shops on the way. Camden coffee house and high wire were both great. The bus is even closer and only costs £1.5. Sit on the upper deck and enjoy the ride!
