We stayed in room 6 which overlooks a courtyard. During our stay and at night it was quiet, although occasionally we would hear some traffic noises and some alarms but nothing that can't be solved with earplugs.
I did like having a code and not worrying about cards or keys. We were able to check in/out by ourselves since we arrived and left very early.
The location of Umma is right on Diagonal Av. and it is a busy street. The bus stops right on front and it is a short walk to the subway. Great location, we were able to go everywhere we needed conveniently.
The room was spacious for 2 people. We had room for our suitcases and were able to hang a few clothes on the hanger and put the rest on the dresses. The room also had a small table with 2 chairs as well.
The bed was comfortable and the bathroom was roomy. Everything was clean and our room was clean and restock every day if we needed.
As someone mentioned, there is no fridge on your room. However, you can use the fridge (and microwave in the kitchen) and store your items there. We did and just labelled them. There are 2 grocery stores within walking distance so you can restock there. We bought some food in La Boqueria for dinner and reheated everything in the microwave for a cheap, delicious and filing dinner.
For breakfast, it is a continental breakfast: toast, ham, cereal, oatmeal, yogurt, jelly, fruit, coffee, milk, tea and juice. We only had breakfast once but Lara made us a small breakfast bag to take with us for our early excursions. Lara was the best! So sweet and also giving us directions and suggestions on how to get there. She made our stay stress-free.
