It is day four of the Syrian truce, and still no civilian deaths have been reported.
Locals in the most devastated parts of the country say the skies have cleared and the sounds of gunfire have silenced.
But much-needed humanitarian aid remains blocked at the Turkish border.
The United Nations special envoy for Syria, Staffan de Mistura, says 40 trucks are still waiting for permission from the Syrian government.
"Final permission for the UN to actually reach those areas has not been received. That's a fact. It is particularly regrettable because we are losing time. These are days which we should have used for convoys to move with the permit to go because there is no fighting. The Russian federation is agreeing with us about this, so are the two co-chairs This is something that must take place immediately."
As part of the deal brokered by the US and Russia, the aid should have been allowed to move unhindered.
Convoys could reach zones such as Moadamiyah, al Waer and Douma in just a few days if the permits were issued.
The coordinator of the UN humanitarian taskforce in Syria, Jan Egeland, accused all sides - the Syrian government, opposition and rebel groups - of wasting critical time.
"Can well-fed, grown men please stop putting political bureaucratic and procedural road blocks against brave humanitarian workers that are willing and able to go serve women, children, wounded civilians in besieged and crossfire areas."
Once Syria's most-populated city and now its most-devastated, Aleppo, is most desperate for the aid.
An estimated quarter of a million people there require some form of assistance, after months of isolation.
Castello Road - the principal route into rebel-held eastern Aleppo - is blocked by government forces who took control in July.
Russia's military says its troops and vehicles have started to withdraw.
Lieutenant General Vladimir Savchenko explains.
"Syrian armed forces are fulfilling the undertaken obligations and has started a staged withdrawal of military equipment and personnel from the Castello road which would allow to ensure unhindered passage of humanitarian aid deliveries into the eastern part of Aleppo."
But United States defence department spokesman Peter Cook says he can't confirm that.
"I do not have right here intelligence and facts right now that would say, one way or the other, whether or not they've done it. We're certainly aware that not all of the terms here, including most specifically the delivery of humanitarian assistance, have been met at this particular moment in time. And we think there is, obviously, an obligation for the Syrian regime to of course allow that assistance to flow. And certainly we would look to the Russians, given their leverage over the regime and their communications with the regime to, as quickly as possible, remove those impediments and allow that humanitarian assistance to flow."
US journalist Bilal Abdul Kareem has spent nearly a month in Aleppo, and says the people's views are not what the West would expect.
He says they're not prepared to sacrifice the possibility of resolving the fight for what they see as a short-term gain.
"The situation here has grown quiet, there's no question about that. There's definitely been a dramatic change. There was a demonstration two days ago, wherein the people were demonstrating that they don't want the aid. They're saying they don't want aid packs, what they want is (to be) able to resume what is relatively a normal life here in Syria."
Mr Kareem says Aleppo residents generally believe that the ceasefire will not hold.
He says rebel groups do not support the truce, and locals expect them to break it.
"No-one here ... while the kids have gone out to the streets to play and people are walking around the streets - there's nobody driving around the streets because there's no fuel, there's no gasoline, there's no diesel fuel, the marketplaces are all closed because there's no food to sell, restaurants are all closed because they can't buy the food to make their products, those people who were badly injured in the fierce attacks in the days leading up to the cessation of hostilities cannot leave because of the siege that's around the city - so, no, nobody is expecting that this is going to lead to a settlement of some sort. No, absolutely not."
Should the ceasefire hold until Monday, which would mark a week, the US and Russia will coordinate their airstrikes on militant groups.
But Russia has claimed US-backed rebels have violated the deal 45 times in the last 24 hours.
The US, however, believes both sides have been guilty of violations.
