Definitely don't book with Smartflats, for the following reasions. 1) I booked a property near where my meeting was. They changed the property location so I was across town and had to take two metro trains each time. 2) It's a real pain checking in as you have to send them scans of your passport, bank cards etc - a time sink; 3) When I got to the property the wifi didn't work. I spent an hour trying to sort it out, including in a chat with a staff person from Smartflats. It couldn't be fixed. The next day it still didn't work (i.e. they hadn't tried to fix it, or didn't care). A really bad experience overall. AVOID.

No wifi available while I was staying because it doesn’t tell me the correct wifi. No response from the office. The worst service ever.
