The apartment was comfortable, self-contained, fully equipped and secure, and ideal for our colleague working nearby. ID of the person staying is required which is easy to supply. On arrival the apartment hadn't finished being cleaned but this was swiftly dealt with, and overall the company is communicative, helpful and easy to deal with. The main downside is that to check in someone from City Relay has to physically meet you there and if you're not able to check in between 4pm and 6.30pm you must pay an early (£30) or late (£50) check in fee. It would have been preferable to collect the key from a lockbox if due to working hours we're not able to check in during the small window given.
