Josef is a wonderful host, incredbily helpful and very responsive to all our enquiries. The apartment is in a wonderful location; easy to walk around, close to the metro, great restaurants and bars on the doorstep and very safe and quiet at night.
The space is prefect for a couple, with plenty of room to spread out.
A note for those with mobility issues or hip/knee problems. The bath is very deep and you need to step into it from a lower point on the bathroom floor. There are no handrails and we were a little owrried about slipping. There is a hand held shower spray over the bath and the best way to get fully showered is to sit in the bath. Getting back up again could be an issue if you have knee problems.
Also, you can only get into bed by crawling up from the bottom. Again, if you have mobility issues, you might want to consider another property.
I understand Josef manages a few properties in Prague and I would highly recommend booking anything through him.
