Alex's apartment was great. I stayed there with a few friends and the entire process with Alex was nice and easy- we never met during check in/out but there were no issues.
The apartment itself is in a great location, just a stones throw from the underground, and if you're arriving from the airport it takes no time at all to get from there to the apartment.
The space itself was top, nice and clean with plenty of space for everyone. 5 stars!
