Some things worked really well, some others didn't. So, to be fair:
Pros
Sean is very nice and reliable, he has been very welcoming and extremely flexible with the check-in and check-out times. He sent us all the useful information about the house a few days before our arrival and always replied to all emails in a short time.
The house is minutes away from a tram stop that brings you straight to the centre, the area is quiet and residential.
Cons
We found the house quite dirty. The bathroom's floor, huge mirror and WC were not clean, the towels were non-presentable, with stains on them and it wasn't clear if they have been used before or they were supposed to be "clean". The kitchen sink wasn't clean and a tub of soapy water has been left there. The room's window has spider webs and draughts, which make the room cold and it's not pleasant as it's behind the bed (I had to fill gaps with toilet paper to stop the air flow). The courtain doesn't work and it's kept rolled up with a string.
The guests' stay in this house can be much better with a few improvements.
