It’s a small apartment in the underground but very cosy and well-equipped. It has great location and facilities. Mirek provided kind, detailed guide and free snacks/drinks. He’s very welcoming and friendly. Everything was perfect except the wifi.
The wifi was a huge problem for us. It was pretty old and always suddenly disconnected and I needed to wait for several minutes to reconnect again. It was quite annoying and happened every 20 min for me.
