We stayed there for 6 nights and the host made us feel at home. Our room was quite big and really clean. The location is good, as the subway is just a few minutes by foot. Also its a bit away from the big loud streets, so during the night its calm and not noisy. The AC was perfectly working, so the room temperature was comfortable even if it was really hot outside,
The host was helpful when you had questions about what to see and booking tours. Also he really was a "host". He even invited us for a barbecue, which was awesome.
All in all the the guesthouse was really good and also for decent money. We would recommend it any time.
