The great location and ability to sleep 9 people were the only saving graces for us.
From check-in requiring our group to wait for an hour sitting on the staircase because the electronic key didn't work, to waiting for someone to turn up with a physical key.. the whole thing was a waste of time and highly frustrating. When it did eventually work, every time someone would come in (at different times) the buzzer would still sound as well as the noisy lock.
Is is worth noting that yes, there are beds to be able to sleep people in, but three of the rooms really are not more than low storage rooms with matresses on the floor. The main two bedrooms are lovely and spacious but the other three can't even have 5-year olds stand up in parts of them.
The two bathrooms were clean and functional - one roll of toilet paper in each one (for a group of 9) of course isn't sufficient. And even with quick showers, the hot water would run out after 5 of us thus leaving 4 people to have a cold shower.
Finally, we were contacted to say they had forgotten to put duvets in the apartment now the temperature was dropping. Since it was still warm in there, we didn't need them and told them that we didn't need them. They had asked us permission to enter the apartment while we were out but we politely declined due to having our laptops, passports, money etc in there (not knowing that visitors would be an option). We got back and they had been anyway. Although all was well, we did not appreciate declining the entry to then have it anyway.
Communication with MIT was quick and they were pleasant, but the reality of this appointment was quite disappointing.
On the plus side, the wifi was strong enough to support work calls (Zoom / Teams), it was clean, light, bright and the kitchen was well-equipped. The location, by Tirso de Molina is great and a very safe area.
