What is the contact information for this guest house, and its exact location (address)?

Thanks for catching that. A previous mapper had tagged the neighborhood as a hamlet and placed the node in the traffic light at the intersection of Kerns and Sleepy Hollow Roads, not the correct position for the neighborhood. I missed removing the highway=* tag when I split them up and correctly positioned the tag. I live on this street and am working on adding some detail plus correcting a few minor inaccuracies.

P-21 является частью национальной системы трасс Туркменистана. Прошу Вас прочитать osm.wiki/Turkmenistan#National_Highways

Это админастративная граница (черта города), не дорога. This is an administrative boundary (city line), not a highway.

No such town as Bukhta Kiyanly exists. This is an industrial site. I am deleting the node and fixing local tags.

Why are these buildings designated as ruins? They are not ancient.

This village is Çarwadar, not Darganata. I have corrected it. Please also refer to osm.wiki/Districts_in_Turkmenistan for authoritative spelling of names of municipalities in Turkmenistan. Best wishes!

Why did you change the English name of the Dinosaur Plateau to something else that is not English ("Dinozor eke")? I have corrected it back to the English name.

"Кислородка"--это заправка для автомобилей?

It is not clear to me what value is added by adding the name:es=hasta la vista tag to this consulate. Perhaps you meant it as a joke but it detracts from the value of the map, so I am deleting it.

Nevertheless, amenity=consulate is correct and amenity=embassy is not. I’ve been a diplomat for over three decades and have served in a consulate as well as multiple embassies, and had the difference drilled into me. Please refer to the Vienna Convention on Consular Relations, which is the international treaty on consulates and consular affairs.

A consulate is not an embassy. I am changing all amenity=embassy tags to amenity=consulate in Istanbul. The embassies are in Ankara, the capital of Turkey.

Кажется Вы нарисовали рельсы на основе отсталой спутниковой съемки. Эти рельсы не существуют. Пожалуйтса не используйте отсталую съемку Bing когда рисуете в Туркменистане если более новая съемка есть. Прошу Вас удалить эти несуществующие рельсы.

You appear to have drawn rail lines based on obsolete imagery. These rail lines no longer exist. Please do not use obsolete Bing imagery when mapping in Turkmenistan if newer imagery is available. Please delete these nonexistent rail lines.

There is no turning circle here.

I'm curious to know why you are breaking up traffic circles I have drawn as circles into segments. Is there a purpose to this I should know about?

Это гостиница. Почему Вы удалили тег tourism=hotel? This is a hotel. Why did you delete the tourism=hotel tag?

Village of Bekibent does not appear on the authoritative list of Turkmen municipalities, either in that or any other alternative spelling I can think of. It may have been disincorporated and abandoned, but without a visit I cannot attest to it.

Gas station already exists, so am deleting this duplicate.
