Soledade, her husband and staff working in the place were amazingly friendly and hospitable. They provided us with everything we needed and even more (for example, when we needed to wash our clothes a girl working there provided us with her own detergent).
The place itself is perfectly clean and one may find everything one needs there. Wi-Fi is working great, a shower as well, they provide you with towels and soap and even with a bottle of water on your arrival, which is a really nice gesture! The only disadvantages are the location (a bit far from Lisbon, however you can easily reach the center if you take the train, it will take you only 12 minutes and the last train is at 1:30 am which is comfortable. There are also trams and buses), and it was a bit noisy in the mornings because the place is located in some kind of basement and you can hear people from the street, however if you are not going to spend all your weekend sleeping till 12 it will be ok cause it is calm and quiet at night.
Overall the experience was great, we would definitely recommend this place to anyone and will probably come back really soon. Thank you for everything, we did enjoy our stay:)
