Mark is a very nice host, always ready to help you with whatever you need. Check-in and communications were very easy and he allowed me to leave the bags before the check-in time.
The room in clean and really big and he also provides a bottle of water, a lot of different types of tea/coffee and some sweets, which is a detail I appreachiated a lot.
I could also use the washing machine for my clothes which is a plus.
The location is not so central but very well connected either by bus or train.
The only flaw was the kitchen: quite messy and the stoves were dirty all the time.
