Tripplo's verdict, based on guest reviews
Tripplo’s analysis · Updated 6 October 2026 · How we review hotels
Nobu Hotel London Portman Square suits travellers who want a calm, contemporary base in the West End. Its address on a quiet square just off Oxford Street is what guests praise most: Marble Arch station and Hyde Park are a few minutes away on foot, and cafés and shops are on the doorstep. The rooms take their cue from the garden in the square, the beds are described as exceptionally comfortable, and the recently renovated hotel is consistently called spotless. Staff are praised as kind and professional, and breakfast wins over many guests. Space, however, is the trade-off. Standard and king rooms are compact for the price, bathrooms can feel tight, and the minimalist look strikes some as bare. Service at breakfast and in the bars can be uneven, and the nightly security deposit surprises a few. Guests who mainly need a comfortable, central room will be happy; those who want room to spread out should book a suite.
Guests score it 8.6 out of 10 — the average across the 23 hotels we list in London is 9.3.
What Guests Loved
- Location is the point guests raise most often. Portman Square is a leafy address just off Oxford Street, Marble Arch station is about five minutes away on foot, and Hyde Park, cafés, restaurants and everyday shops are all close at hand.
- Guests keep coming back to the beds, which they describe as sublime, with soft bedding that makes it easy to sleep well after a long day in the city or a flight across time zones.
Things to Consider
- The most common complaint is room size. Several guests found the standard and king rooms small for what they paid, and the bathrooms tight; one also found the minimalist styling rather bare. The suites and family rooms are described as far more spacious.
- Service is not equally polished everywhere. Some guests found breakfast staff inattentive or the restaurant slow, a few met a cool welcome at the front desk, and one felt the terrace bar team was less friendly than those in the lounge.
Should you book it?
Nobu Hotel London Portman Square is worth booking for shoppers and sightseers who want to walk to Oxford Street and Hyde Park — but pick somewhere else if you need plenty of space in an entry-level room.
