We were in a pinch for a place to stay in London for one night. The night before, I was able to book a room and Donovan was very helpful in providing instructions for getting to the flat, with detailed instructions if you were arriving by tube.
You share this flat with two other people in two other bedrooms, so just be expecting to see whoever is staying there when you check in. Regarding check in, make sure you read the fine print and know that you will be asked to check out at the same time you check in the day before. I was unaware of this so was forced to check out earlier than I anticipated, but luckily it was only half an hour. Just something for everyone to be aware of.
The room and common areas and bathrooms were all clean with fresh towels.
Having access to a washing machine was great. The electric fan was extremely clutch considering it was very hot the night we stayed there. Donovan also provides breakfast cereals, coffee, milk, and sugar, which was a nice touch. Would stay there again if in the Waterloo area!
