I want to be clear...the location is excellent, the property was very clean, the check-in process was good, and the property manager got back to us quickly -- but this is an extremely expensive property to stay at and so the expectations are, unsurprisingly, going to be equally high.
The internet connection was not good and there's no service in the top bedroom to the left as you come up the stairs. They sent someone around but said they couldn't do anything, and also contacted the service provider but we never heard back. This meant we couldn't run our baby/toddler camera which was far from ideal. And generally doing work from the property was frustrating. For the price (and frankly any rental property), solid internet connection is something you have to nail and this wasn't.
Smaller frustrations, again for the money, built up. We stayed at the property for 9 nights but only received a small bottle of shampoo/conditioner in each bathroom, and the kitchen was understocked with some basic items you would expect to be in there - such as having more than 2 tupperware containers, there was no cling film or aluminum foil or parchment paper - a few basics that don't cost much to add.
The door to the balcony screeches when you open/close it - again, very easy to fix but overlooked. The toaster broke but they did send that over ASAP so that was perfectly fine and appreciated.
If the property had been 30% less expensive, these become less of an issue (outside of the internet).
