We had a great stay at Alena's. I wish I could give it ten stars for location - the flat is about a minute's walk from the Old Town Square. Try the friendly bar on the street downstairs! The building is very historic and occasionally feels it - five people was a test for the hot water, and there is an odd arrangement where a neighbour has a storage area that looks into the bedroom window, and woke us up one night. But that is the price of staying in the historic centre - it was clean, check-in was very easy, and it was a great base for a lovely stay in Prague.
