Welcome was functional but not very enthusiastic, neither was the farewell from the same member of staff the next day, they just took the key and that was that. I feel the staff could be trained to be a bit more welcoming.
Room was clean and comfy, bedding fresh and mattress just right, excellent shower and hairdryer and small ironing board and iron provided as well as tea and coffee tray. My only criticism is a smell of stale cigarette smoke which seemed to linger the whole time. Secondary glazing was effective, I didn't find the noise a problem.
I had a walk around the nearby sights, the Fitzrovia Belle is well placed for Trafalgar Square, Oxford St, Downing Street, Chinatown, Buckingham Palace, The Mall etc although I did do 20k steps in a little over three hours! Euston station is just 10 mins away, Goodge St 3-5 mins away, Tottenham Ct Rd Elizabeth Line station is 15 mins walk, excellent service (I went to Liverpool St but Paddington and Heathrow easy to reach on this line too)
I had a couple of pints of Guinness in the bar and Big Belle burger and chips. Both were excellent. Not cheap but the prices are online so can be checked before you book. Burger was high quality.
Food service was quick, breakfast included is either standard cooked breakfast or continental, not both.
