Had a great time in the appartment.
Communication with Paola(Marko's assistant who handles the appartment guests) was great, she is a joy to talk with.
Location is unbeatable - right at the piazza del Popolo which is equally beautiful at morning and at the evening.
Sound proofing is amazing, you can't hear the outside, it doesn't disturb your sleep in the slightest.
Conditioning is working great which is a must.
Internet is really high speed, without any issues.
The flat has everything you need for short or long stays.
