My husband and I thoroughly enjoyed our three-night stay at the Golden Angel. The communication with Prague Residences (the company has are multiple locations) was prompt and very helpful in answering questions. The location in Old Town was central and convenient, yet the building was quiet. Key Code entry was great and never failed.
The only flaw, and a very minor one, was that the second elevator was out of order during our entire stay. Fortunately it was not a big problem, just occasionally a longer wait. And using stairs were an option.
