A very important factor that is not stated in the ad, is that the appartment is on the 4th floor with no elevator! This should be stated clearly in the ad's description or in the confirmation contact from the host. Just not mentioning it in the amenities, or having to search through the comments to find out, is not enough. For some people it would be the deciding factor for (not) selecting the appartment!
On the other hand, the appartment was clean, tidy, in a good location close to Metro station, with necessary equipment and the host offered immediate communication. If it wasn't for the elevator (or clearly stated for those who don't mind), it would be a very good opportunity!
