Pros: The location was amazing, and the self check-in was smooth. The unit (Apartment 06) is spacious and has all the necessary amenities (kitchen, kettle, wifi, washing machine). City Relay responded quickly.
Cons: The cleaner was still working when I arrived at the scheduled 4pm check in time and was not finished for another 2 hours so I couldn't check in until very late (which after a long flight I found quite tedious).
There was a persistent smell; even if the apartment is non-smoking it's clear the neighboring apartments are not and it was pervasive.
The unit itself has noticeable stains and its furniture needs repair -- particularly the sofa -- and the peeling paint on some of the walls. When the toilet broke, no one was able to fix it for the remainder of my stay (one additional night) though City Relay did respond to my maintenance request quickly.
