Great location, nice building, sunny apartment on quiet street. The Posh Properties 'Passport' arrangement for 'check in' was overly invasive, complicated, confusing, and showed how working through yet an additional party through Airbnb can add to potential problems. Aside from the difficulty of getting the key to work in the door on a very cold evening when there was apparently noone available to help us enter the building, the plumbing in the bathroom toilet and shower backed up almost as soon as we started to use it. Apparently no plumbers were available to remedy the situation so we ended up living with this major inconvenience for two of the three nights. We feel that Posh Properties should have been managing the maintenance issues better so that plumbing problems could have been averted.
