My friend and me stayed with Mike in November. If you're looking for an affordable central location with some privacy to catch a good night's sleep after long hours of sightseeing, shopping and going out, this is the perfect location. The bunks are comfy to sleep in, Metros are literally at the corner and you can take nice walks in the area.
Plus Michael is a really nice host, he helped us with our luggage, prepared the beds fresh when we arrived and provided us with good advice for exporing the city, an extra key and our own electric heater, all of which made our stay with him very convenient.
The building and flat have some antique charm which gives them a nice flair both of us really liked but I see that depends on personal taste and expectations. In case you rather expect a modern equipped, clean-chique surrounding you'll probably be happier in a hotel.
