Flat was lovely and spacious, modern and high tech and warm but surprising quiet for a basement flat in London so close to oxford street (10 minute stroll). There would be more than adequate space to use the airbed and/or cot if needed.

Spare bedding and towels were easily found and more than adequate supply.

Key safe also made it convenient for checking into the flat and throughout the stay (no need to try and organise a specific time with landlord and rush to get there).
Landlord checked in during our stay but we had no issues or questions.
