Malcolm always answered very promptly, which was very helpful. You may have to call/text him though instead of going through the app.
The location is super convenient. We also asked Malcolm for a kitchen scale and mixer because we wanted to do some baking and he more than delivered. Light sleepers may be bothered by the noise coming from the street but we had no real issues with it.
The only problem we had was that the apartment hadn't been dusted very well and that there wasn't any shampoo or body wash.
Overall would recommend, we had a really nice time.
