plenty of space downstairs, and themain bedroom is plenty spacious as well. the other two are a bit smaller but the whole apartment is great for a long or short stay. we were there for 9 days, mom, dad, and our adult son. totally central location, and at the 'quiet end' of the Temple Bar neighborhood. it really was relatively quiet, and if the windows are closed they kee the occasional loud talkers in the street from disturbing your sleep.
it worked out really well for us, Michal was an excellent host.
