As far as the location and apartment itself are concerned, we had a positive experience and we highly recommend this place for many reasons, that have been listed here countless times.
We'd like to add though, that we had to jump through unexpected hoops from the so called host's side, that put us through unnecessary stress and anxiety: As soon as we were confirmed and our money had been taken, we were informed to sign a long and extensive contract independent from Airbnb for the so called hosts property management company, Air Peace of Mind. On top of it, I was forced to upload a photo of myself, without which we were refused the checkin information, although guaranteed by contract from Airbnb 3 days before checkin. This subcontract should be openly presented on the Airbnb site when booking this apartment.
In fact this highly stressful situation, dragged on until 2 hours before the cancellation deadline, when I gave up finally and had no choice but to sign this contract. We very well understand, that many other guests have been in the same situation, pressured into this contract, especially when they would come from a different continent and had booked the flight way in advance, as we had. All this time, Emily herself kept on communicating with us in vague terms, that let us doubt her very existence. In fact you will never meet her, and the person who helped us out in the awkward key handover procedures, was not her, but another employee of the management company. He spared us picking up this key a mile away at a small kiosk. Imagine, you will be rolling your luggage back and forth through Portobello Rd, in the midst of a stream of tourists. There are many shops and stores just around the apartment, but nevertheless they make you walk a mile in order to pick up the keys at this distant, inconveniently located kiosk. It is beyond us, that not more people have described this ridiculous, time consuming check in procedures. In the end the company must have felt our stress and a representative did meet us at the door to introduce us to the apartment, which is however not their standard procedure.
