Marco's appartment was great. It's very big (we were a group of 10) and very well located in La Latina. Can be a bit noisy but if you close the windows, it's alright.
The entry procedures via the app are very convenient for large groups, but sometimes it bugs and the bottom door doesn't open, which is quite annoying.
Marco is very responsive when needed.
Only downside is the checkout at 11 which is early and not flexible at all :/
Would recommend anyway!
