The location is great, across from Regent Park and around the corner from the Sherlock Holmes museum and Madame Toussauds but in a proper neighborhood. It is an easy walk to Marylebone and it's great shops and restaurants. Easy connection to tube or buses to head to Notting Hill or Shoreditch is easy.
The space is clean, quiet, and light filled. Nicely decorated. Check in is easy.
The only complaint after 3 nights is the mattress is a thin 4 inch mattress from Ikea which left me and my husband achy each morning and would wake feeling the frame underneath each night.
