I spent a month in Jiří's apartment on a business trip. The checkin was smooth with his really nice wife. The apartment has a great, central location, close to all the touristy things, yet looks to a quiet inner courtyard so the crowd's noise is not a problem. It has most amenities needed for a comfortable stay, the kitchen is equipped so one can cook simple foods too. It has a separate table for work, so it's suitable for home office too. Also, it has great public transportation connections, so it's easy to travel the city from here.
