Nikoloz was very nice, he was waiting for us with the key. He answered the phone every time we called. The place is very clean and centrally located. It takes approximately 7 min to walk to Charles Bridge. 5 min to the tram stop. The bathrooms are shared, but we never had a problem with the other guests. The neighborhood is very safe, there are many police around since it is very near the embassies. Thanks Nikoloz.
