We thoroughly enjoyed our stay at Anna and Alena's apartment and would recommend it to other travellers.
It is in a wonderful location, in easy walking distance of all the main tourist attractions and close to a metro station and small supermarket.
The apartment was clean and tidy with modern furnishings. We were pleased to find it well stocked with kettle, towels, microwave and hairdryer. As other reviewers have said, there are stairs up to the bathroom and up to the apartment itself. We didn't find this a problem but it is something to consider if you are less fit or intend to enjoy lots of Czech beer.
Alena was a caring host who made us feel very welcome - thank you!
