the reason for only four stars? the stairs. they are very steep stairs, with a turn midway so for anyone with difficulty climbing, or anyone with large or heavy suitcases, they could be problematic.
othewise this is a very nice apartment, cheerful, good natural light very comfortable. excellent location for walking everywhere! kalsa area has great atmosphere, beautiful old buildings, interesting alleyways, diverse population. there are a lot of tourist stays, but it still feels like a neighborhood.
