The room felt bigger than in picture and was modern and perfectly clean. The bed was good and the bathroom and kitchen all we needed and more. Location is as central as can be. Fabio was very friendly and gave us a 10-mn tour of the facilities but also documentation on Porto and answered all our questions.
Only small downside was the small side heater - not enough to warm up the whole room on a cold December night (although should not matter the rest of the year) and the thin windows letting in the noise from the outside (but only on the Friday night when cheerful people were being loud in the street).
Overall great experience and the price for two was reasonable, very recommended.
