We only ran into Mark once and he was very accommodating and generous. The entrance to this apartment is on a busy street with lots of noise but the apartment itself is VERY quiet. Surprisingly so. The place was clean, comfortable, and well maintained, a good place to use as a launching point to explore the city and a nice quiet place to return to in the evening. The location is very convenient, we walked everywhere during our stay because the weather was so nice but public transportation is readily available as well.
