London hotel rooms for three people

3 adults in one room is not so much a thing here other than in prisons. Maybe Premier Inn or aparthotels like Citadines?

Premier Inns are a good choice.

Premier Inns only allow max 2 adults. The Travelodge chain allows 3 adults to share. It is another budget brand like Premier Inn.

At one point the now Meliá London Kensington on Gloucester road had at least one room for three people. We stayed there with my daughter. While we all shared the bathroom, there was a door separating our room from hers and it had its own television. On its website Melia calls it a Junior Suite, or an even bigger Suite and the room is referred to as a lounge with a sofa bed.

Helen has given you inaccurate information about premier inns. Some certainly do allow 3 people in a room. Premier Inn at Paddington Station has family rooms. Click on the link then scroll down towards bottom and click on family room tab.

I just booked a family room At Premier Southwark with a large adult bed, a small adult bed, and a pull-out bed.

+1 for the “Family Room” option at Premier Inn, which is where the three of us are staying next week (Kings Cross) at a very reasonable rate.

Some certainly do allow 3 people in a room. Premier Inn at Paddington Station has family rooms.

The OP needs a room for 3 Adults. While Premier Inn has family rooms for 3 people, a max of 2 adults are allowed. The other has to be a child under 16. Go back and check the link. The drop down for booking only allows you to select 2 adults.

Yes exactly that. They do allow up to 4 people but only 2 are allowed to be over 16.

I suggest you search using booking.com. Put in 3 adults and your favored location. Once you identify some prospects, go to the hotel’s own website to book. Expect the price to fairly high.

Hampton by Hilton Waterloo would be my next suggestion.

The Lime Tree Hotel in Belgravia has triple rooms. We are staying in one in June.

These two hotels have rooms to accommodate three people;

The London Elizabeth Hotel has rooms for three adults.

We had 3 adults in a room at The Resident Covent Garden. It was tight, but doable for a couple of nights.

We’re traveling with my 17-year old son and need the same thing. Booking.com can help find options.

I, also, am a fan of booking.com. Good site for research as well as booking
