We stayed in Fema's appartment for 5 nights, there were 4 of us.
We thought the appartment was great and communication was very simple and efficient.
And in the appartment, there are a lot of little messages or attentions just there there to make your stay more pleasant. You feel welcome and it is very efficient.
We checked in on our own, keys were in a lock box.
As someone mentioned, the appartment is slighly bigger than what I expected from seeing the photos. It was very clean, looked great, as the photos show, but it's better in real life
Location is good. There are various restaurants just around the block, from German traditional cuisine to indian food, a couple of antique or resale shops. U-bahn station is also on the same block. We parked our car when we arrived and took it back when we left, parking is free but it doesn't seem that easy to find a spot, which might be a good thing : once you parked, you leave your car there. Also, I believe the appartment is right outside of the low emmission zone, which is good since we didn't have the sticker.
Inside the appartment, it is also nice: our teenagers slept on the large (sturdy) bunk beds and I guess, if we had had only one of them with us, the bottom one would have been replaced by a couch. The top one, allows some kind of privacy, which is good.
We are very happy from our stay. Thank you!
