The place was absolutely didgusting, the room smelt like someone had died in it, constant banging all night and you could here people
Outside all night through the poorly maintained windows… we had ants in the room!
I stayed at Thanet Hotel Annex during my visit to London. The location of the hotel is very convenient and close to many attractions and public transportation. The employees were also very friendly and helpful during my stay.
However, the hotel building needs some improvement. The walls and floors are not well insulated, and it was easy to hear noise from the upstairs floor whenever someone moved around. This made the room less quiet and comfortable at times.
The step from the bathroom down into the bedroom was about 14”. My husband and I are in our late 70’s and both of us fell out of the bathroom onto the bedroom cement floor. Fortunately, we weren’t hurt.
The Annex is a nightmare!
Absolutely shocking room. It’s was rotten! The cleanest thing was the bed sheets. We had tissues under the bed from previous travellers. Toilet didn’t work properly. Hair in the bath room sink , couldn’t open the window in this awful heat. We will never book again. If I could give no stars I would . AVOID!!!
Disgusting! Avoid at all costs! Dirty and mouldy room, everything is chipped and in disrepair. No towels provided, the linen smelled like womens perfume, pillows stained and uncomfortable. Very uncomfortable bed. Cold room. No TV remote. Constant humming noise at night. Felt like descending into Dante's inferno.
Wow, this place is atrocious. Very very unclean bordering on dangerous. Black mould in rooms. I want a refund

Room could do with a fresh paint and update, bathrooms need a good clean and up do,but otherwise it was a pleasant stay for one night, receptionist guy was friendly and lovely
Ideally placed for supporting family in Great Ormond Street Hospital, also very close to the British Museum.
Lots of shops and places for food near by.
