I began staying at the Euro several years ago, and have only stayed in a different place once since then. I consider the Euro to be a basic B&B - you enter into a small hallway which takes you into the reception area and breakfast room.
The rooms are small and simply furnished, but perfect for single travelers or budget travelers. The rooms with shared bath have a bed, desk and a sink. There is a good sized closet, a hotpot with tea and coffee packets, and a tv. The hotel will lend you a hairdryer or an iron if you need one.
Unlike B&B's from a few years ago, they clean the rooms, change the towels, and replenish the coffee/tea on a daily basis. A full English breakfast is served, along with juice and cereal choices. The staff here is very friendly and helpful, and the hotel is in a very convenience location in the Bloomsbury district. It is within quick walking distance to Russell Square tube stop, as well as Kings Cross and Euston stations. I would recommend this hotel to anyone visiting London!
