Comfort Inn Hyde Park appears to be in a building converted into a hotel from a different use. In doing so, the hotel did everything possible to fit as many rooms as possible into as small a space as possible. As a result, the rooms are unbelievably small - forget US standards, the rooms are small even by European standards. The building and rooms show their age. The hotel provides continental breakfast, which is edible, but do not expect much. Most of the bakery items (breads, packaged croissants) were stale.
The bathroom, of course, was also very small and poorly designed. The sink is so small that you cannot wash your face without getting the floors wet. The shower ran out of shampoo / soap, which was not replaced. There was, however, good water pressure, good hot water.
On the positive side, the hotel is located in a safe and pleasant area that is close to two tube stations (within 5 minute walking distance). The staff are friendly and helpful.
