Mark is a great host. He answers very quickly.
We stayed 1 month. Mark made sure the place was very clean when checked in. The place was tidy and comfortable. We were especially thankful for the heater and additional kitchenware he bought immediately after we asked for it. That was fantastic! There is enough space for 2 people. I loved the kitchen, especially the gas stove. It can be a bit noisy since the apartment is next to a main road and on ground floor (dust will easily enter if you leave the windows open for too long). It was also a bit chilly in the winter nights (older style apartment with poor insulation)
But overall we liked it and can definitely recommend to stay.
