Small but adequate space for our needs (two adults). Location was wonderful (very close to Paddington Station, Lancaster Gate tube stop, and Hyde Park). The unit itself was clean and tidy, with many essentials (basic cookware, utensils, etc.) We did feel that the building and building management could be improved -- the hallway leading to the unit had an unpleasant odor of mothballs and something funky (I suspect something once spilled on the carpet and it was never properly cleaned, leaving a remaining smell). But once inside the unit, it wasn't an issue. There were a few things here and there which could have been better: a small wastebasket in the bathroom (especially helpful for women), an additional shelf or hook in the bathroom (no space for toiletries), blinds or sheer curtains on the windows (would have allowed light in while still offering privacy from neighbors), a bedside lamp. The biggest issue, however, was that there was no way to get in touch with anyone on-site for maintenance issues. Three days into our stay we noticed an alarm from a smoke detector going off somewhere nearby in the building. We notified our host, who responded 24 hours later that he had reported this to the building management, but the issue was never resolved. We slept with earplugs for the rest of the trip, and even tried to contact management on our own, but the fact that there was an alarm for the remaining five days (and nights) was really disruptive.
