This set was very pleasant to build for me and my wife as it reminded us many scenes from our favourite TV series. There is a lot of small details with many episodes of the series. It is also cool that with minor changes you can present different scenes, e.g. Ross playing piano.
Build - it was not complicated (~30% of set was builded by my 4 year old daughter). Build satisfaction was on ok level, there was no WOW effect. Playability - it is very high due to partially modular build. We play with this set really often, even with kids (3-4 years) that are not into show. Minor minus of the set: some elements are fragile and detach easily(chairs, pillars)
