May was very welcoming and friendly, with fast responses to any questions online. The room itself was a good size with ample amounts of storage and lots of plug sockets. The ensuite was nice and spacious and modern, with a fantastic shower (shower gel/ shampoo provided). The only things of note for those not used to noisy cities is that it was a little noisy at night, with thin windows I think, but soon got used to it and not all that bad (I've had worse!). There also wasn't any coffee provided (just tea and a kettle), but as there were many coffee shops right outside, that wasn't too much of an issue.
The location makes up for it, as you really are right in the middle of London, a short walk away from a bus stop and underground and a large Sainsburys round the corner. We enjoyed being able to walk to the theatre, the cinema and restaurants, as well as Buckingham Palace.
Overall, was a lovely stay, and would stay again!
